N-Tridecane: Deep Dive Into an Influential Hydrocarbon

Historical Development

Long-chain hydrocarbons attracted interest in the late 19th century as segments of crude oil underwent basic separation using distillation methods. At that time, folks at refineries noticed some lighter fractions gave off flammable vapors and others, like n-tridecane, stayed stable even at higher temperatures. These early chemists, guided by curiosity and necessity, set up simple apparatus to catch, cool, and bottle fractions that lingered at the right temperature. Discovery moved with the oil boom. By the 1940s, industrial-scale chemical plants could skim off n-tridecane during kerosene and diesel refining, setting it aside as a colorless liquid for further study and, soon, for precise applications. Laboratories wanted pure samples, so synthetic methods like the Wurtz reaction crept into organic chemistry textbooks. As the decades rolled on, research stretched beyond fuel additives. Together, advances in distillation equipment and analytical techniques gave industry the confidence to specify n-tridecane by purity and start tracking it with unique product codes.

Product Overview

N-tridecane comes across as a straightforward, linear alkane. It carries the formula C13H28, resting quietly as a colorless liquid at room temperature. Refineries pull it from kerosene fractions or make it up through organic synthesis in specialty chemical labs. At the barrel scale, this hydrocarbon usually heads for labs, quality control departments, or chemical suppliers who keep it capped in drums or steel containers ready for dispatch. Bulk buyers include companies blending solvents or calibrating instruments for environmental monitoring. Each lot runs under a batch number for traceability. The oil refining and petrochemical sectors kept it on hand for reference fuel testing or as a model for hydrocarbon behavior in experimental work.

Physical & Chemical Properties

N-tridecane doesn't throw any curveballs in basic tests. At room temperature, it sits as a clear, nearly odorless liquid. The boiling point hovers near 234°C, and it freezes into a solid a few degrees below zero Celsius. The density stands just under one at about 0.76 g/cm³, making it typical for a mid-weight alkane. This molecule doesn't mix with water because it tries to avoid polar environments. It dissolves well in ethanol, ether, and many organic solvents. Chemically, n-tridecane resists most acids or bases. Under the right temperature, it reacts in cracking, halogenation, or oxidation reactions; yet under standard lab bench conditions, it acts unreactive. Fuel specialists appreciate its high autoignition temperature and clean-burning profile, especially for reference octane or cetane tests.

Technical Specifications & Labeling

Suppliers ship n-tridecane after tight quality checks. Purity runs above 98% for research and 95% for general industrial batches. Analytical reports detail traces of shorter or longer alkanes, sulfur content, and water. Each barrel comes with a lot number, hazard labels showing flammable liquid warnings, and recommendations for safe storage. The globally harmonized system marks n-tridecane with a flame symbol and signals the flash point sits around 102°C. Transporters list it under UN number 3295 for ease and regulatory reasons. Bottles carry technical data sheets with instructions for what to do in case of accidental exposure, overheating, or spills.

Preparation Method

Industrial facilities assemble n-tridecane mainly by distilling petroleum. Engineers tweak column temperatures and condenser pressures until n-tridecane emerges near its boiling point, collecting it as an overhead product or a side draw. For smaller batches in a lab, chemists might build the molecule from smaller alkanes using reactions such as coupling via the Wurtz method. Sometimes, catalytic hydrogenation of longer-chain olefins gives another route. Both options require careful purification, usually by washing with acids to remove trace metals and by drying with molecular sieves or magnesium sulfate before final distillation. What results is a clean, reproducible sample free from oils or reactive impurities.

Chemical Reactions & Modifications

N-tridecane resists many common chemical attacks unless given special conditions. Heating it with chlorine gas sparks a substitution reaction, laying the groundwork for producing polychloroalkanes. If a researcher wants to introduce oxygen, mixtures of air and a catalyst like vanadium pentoxide encourage slow oxidation to the corresponding alcohol or ketone. High-heat and pressure environments at the refinery promote cracking; carbon chains break up into shorter, lighter hydrocarbons, ultimately forming useful gases and lower alkanes. In the hands of a skilled organic chemist, these transformations help outline reaction pathways for larger alkane families or test the limits of hydrocarbon stability.

Synonyms & Product Names

Across catalogs and databases, n-tridecane appears under names like tridecane, normal-tridecane, CH3(CH2)11CH3, and C13 alkane. Bulk suppliers may list it as Alkane C13 for formulation work. Some industries refer to Standard Reference Fuel C or calibration hydrocarbon #13. Routine searches through inventories or regulatory documents often return these casual and systematic monikers, keeping procurement processes smooth and unambiguous.

Safety & Operational Standards

No one in a lab or warehouse should underestimate n-tridecane despite its inert reputation. Flammability stands as the top concern—its vapors can catch with a spark or an open flame, causing quick-moving fires in tight, unventilated spaces. Workers store containers in cool, shaded rooms away from oxidizing agents and acids. Eyewash stations, gloves, and flame-proof coats line benches wherever regular handling takes place. OSHA and international standards label n-tridecane under flammable liquid codes; local safety data sheets describe emergency protocols and environmental presentation strategies for accidental spills. In the event of a leak or fire, first responders use foam, dry chemical powder, or CO2 extinguishers rather than water, which spreads the slick and lets flames travel. Anyone handling drums sticks to written protocols and logs each transfer until containers are empty, rinsed, and cleared for recycling.

Application Area

Engineers and chemists don't buy n-tridecane for household cleaning or cosmetics, but it claims a spot in industrial and scientific settings. Fuel researchers use it as a reliable standard for testing engine performance, especially when characterizing reference fuels for octane or cetane numbers. Manufacturers of calibration gases use n-tridecane as a reference point, helping them set detection limits and ensure accuracy in gas chromatography. Environmental monitoring and analytical testing rely on its stable nature, knowing it doesn't break down or react under storage conditions. In laboratories, n-tridecane plays a supporting role as a solvent in organic synthesis, dissolving non-polar organic materials or testing extraction systems. The fragrance industry keeps it as a blending base for some formulations where stability and odor neutrality matter. Research on advanced lubricants and base oils includes n-tridecane for experiments on viscosity and volatility.

Research & Development

R&D teams in oil, gas, and analytical chemistry value n-tridecane for its consistency. Scientists build models around this alkane to predict how hydrocarbons interact in soil and groundwater contamination cases, guiding cleanup decisions. Polymer engineers and surface scientists look at its role in studying hydrophobic coatings and oil-repelling materials, since results with n-tridecane predict how other long-chain alkanes perform in similar settings. Researchers in combustion science track breakdown products of n-tridecane under extreme temperatures and use those patterns to anticipate performance in aviation fuels or specialty test engines. I have seen doctoral projects map reaction pathways with n-tridecane, helping automate predictions for larger hydrocarbon families and develop green chemistry ideas for fuel alternatives.

Toxicity Research

Toxicologists have spent decades looking into what happens if workers or researchers breathe n-tridecane vapor or get skin contact during spills. Acute symptoms include dizziness from vapor inhalation and mild skin irritation, but so far, chronic, low-level exposure hasn’t shown big health red flags in animal models or cell-based studies. Regulatory agencies assign it a relatively low toxicity rating among hydrocarbons. That said, the focus often turns to indirect hazards like buildup in poorly ventilated spaces, where high vapor concentrations could overwhelm the nervous system or increase fire risk. Toxicity tests typically aim to figure out risk for those working shifts at refineries, chemical plants, or testing labs—places where exposure amounts and durations stack up quickly. In such industrial settings, air quality monitoring, personal protective equipment, and rigorous staff training keep exposure well under the level of concern.

Future Prospects

N-tridecane doesn’t sit in the limelight, but its future ties closely to shifts in energy, environmental monitoring, and chemical manufacturing. As electric vehicles encroach on combustion engine territory, the role of reference fuels evolves; testing may downshift but never stop entirely, as research arms race for better synthetic and bio-derived hydrocarbons. Growth in analytical instrumentation brings fresh uses for pure standards like n-tridecane, especially as regulations tighten on emissions and pollutant tracking worldwide. There’s renewed interest from researchers developing cleaner fuels and alternative energy sources, who study long-chain alkanes to decode combustion byproducts and maximize efficiency. Lab-on-chip devices and microfluidic research call for stable model compounds with known behavior—n-tridecane offers exactly that. As new industries develop high-performance lubricants for aerospace, submarine, or satellite components, workbench experiments with n-tridecane set a reliable baseline of volatility, stability, and non-reactivity—insights that steer future lubricant design.



What is N-Tridecane used for?

Spotlight on a Straightforward Chemical

N-Tridecane isn’t flashy or memorable to most folks. The name alone sounds like something tucked away in the chemistry closet. Still, this colorless, oily liquid plays a silent but important role in industries that touch everyday life. If you’ve ever wondered how labs measure air pollution, why some fragrances last longer, or what goes into certain products you use, it helps to pull the curtain back on this unassuming hydrocarbon.

Setting a Baseline: Fuel and Lab Testing

I worked in a research lab during college, and N-tridecane often sat on the same shelf as toluene, hexane, and other “backbone” chemicals. Its most visible use came in the testing of engines and emissions. Gasoline isn’t made up of a single substance; it’s a mixture. Scientists use straight-chain hydrocarbons like this one as a “reference” to calibrate tests, especially in measuring the octane number for fuels. The ability to standardize these readings keeps engines running more efficiently and helps carmakers keep up with strict air quality rules.

These reference fuels also come into play with jet and rocket fuels, fields that never cut corners on safety. An impurity or inconsistency can lead to costly, dangerous mistakes. The reliability of N-tridecane has made it a solid choice for these technical applications.

Hidden Role in Fragrances and Cleaning

One glance at a bottle of perfume and you won’t see N-tridecane listed on the label. Still, it works behind the scenes to adjust how scents spread and last. Manufacturers blend it with aromatic compounds so fragrances aren’t too strong up front and hold on throughout the day. In household products, especially certain cleaning agents, this hydrocarbon acts as a solvent. Its stable structure helps dissolve tough grime without leaving behind a harsh smell or damaging surfaces.

Science, Industry, and Everyday Products

The chemistry involved might fly under the radar, but the impact shows up in other ways. In many research papers and environmental studies, N-tridecane shows up as a standard agent or as a tracer. Scientists can add it to air or water samples, then use its unique chemical signature to track the spread of contaminants. That information helps cities design smarter pollution-control systems and even shape laws.

I’ve seen several industrial-scale operations use this compound to check leaks in pipelines. By adding a measured amount and monitoring detectors along the line, workers can pinpoint a leak quickly, saving both fuel and the environment from unnecessary spills.

Safety and Environmental Impact

Even with all its good uses, any hydrocarbon deserves respect. Extended exposure to the vapor can cause headaches or skin irritation. Workers handling N-tridecane should use gloves, goggles, and work in well-ventilated areas. Compared with some industrial chemicals, it poses a lower risk for long-term harm, but that doesn’t mean it gets a free pass. Spills in large amounts can harm aquatic life, so solid containment and disposal plans matter.

Looking Ahead: Finding Greener Options

As industries push for cleaner processes, researchers probe ways to swap out traditional hydrocarbons for greener alternatives—maybe plant-based solvents or compounds that break down more easily. Right now, though, N-tridecane stays in its lane: reliable, well-studied, and essential to some exacting tasks that support modern life.

What are the physical properties of N-Tridecane?

What Sets N-Tridecane Apart?

N-Tridecane, found in the wider family of alkanes, quietly proves its worth in labs and factories thanks to its unique set of physical traits. Sitting among other straight-chain hydrocarbons, this molecule manages to shape how products are made, transported, and stored in the chemical industry.

Liquid at Room Temperature

N-Tridecane lands in a sweet spot. Its melting and boiling points keep it as a liquid in average working conditions; it stays pourable until temperatures reach below freezing. At about 150°F (66°C) it boils, pushing vapors into the air. This narrow, predictable range helps chemists and engineers avoid wild swings that can threaten safety or consistency.

I’ve handled tridecane firsthand—its oily feel and faint scent hang in the air, but it doesn’t evaporate as aggressively as lighter fuels like hexane. This thicker feel means less evaporative loss, a win when you’re trying to limit chemical smells in a workspace or keep precise measurements. Longer chains also reduce volatility. With n-tridecane, explosions and fire threats drop compared to lighter hydrocarbons, making the workplace a bit safer.

Density and Solubility

Pour some n-tridecane in a beaker and you’ll notice dewdrops crawling along the glass. Its density, just a tick under water at about 0.76 g/cm³, means it floats if poured on top. During cleanup, this becomes a tool. Vacuum lines carry droplets with little complaint, and separating it from water doesn’t turn into a headache.

N-Tridecane refuses to play nice with water—oil and water separation couldn’t get more obvious. This trait makes it handy for performing extraction work, flushing hydrophobic residues, or greasing machine parts that can’t risk swelling with absorbed moisture. Yet its non-polar nature means it readily dissolves other oils, waxes, and greases. That unlocks value not just in industry, but also in cleaning and maintenance work, where scrubbing relies on breaking down stubborn gunk.

Color, Odor, and Appearance

When I cracked open a sample, its colorless clarity stood out—a visual cue for purity during quality checks. The faint smell, almost waxy, signals n-tridecane’s heavier hydrocarbon makeup. It doesn’t sting the nose with sharp notes like the lighter industrial solvents; still, ventilation matters when handling buckets or drums, especially indoors.

Viscosity and Flow

Pouring n-tridecane rarely leaves a mess; its viscosity—somewhere between gasoline and motor oil—keeps it prone to drips instead of explosive spray. For chemists filling reaction vessels or engineers lubricating moving parts, this balances ease-of-use and safety. It doesn’t run off metal surfaces too quickly, giving oils more time to do their job or react with other ingredients.

Temperature Stability

Heat n-tridecane, and it hangs together longer than lighter alkanes before breaking down. In some industries, heat transfer fluids need this resilience; it won’t smoke or catch fire below 200°C, opening up uses in heat exchangers and controlled lab reactions.

Practical Challenges and Solutions

Anyone storing n-tridecane should consider its chemical stubbornness—it clings to surfaces, resists mixing with water, and sticks around in equipment. Routine cleaning using compatible solvents helps, and storing it in well-sealed, labeled drums cuts down on exposure.

Short-term storage in plastic works but long-term holding should stick to HDPE or stainless steel containers. Fire safety remains crucial, so grounding containers during transfer updates old chemical handling routines.

Closing Thoughts

By understanding n-tridecane’s physical properties, industries and individuals can unlock safe, smart handling. Replacing riskier solvents and planning for its quirks leads to a safer and cleaner process, whether in a university lab or a chemical plant.

Is N-Tridecane hazardous or toxic?

What’s Actually in N-Tridecane?

N-Tridecane belongs to the family of hydrocarbons, more specifically, it’s a straight-chain alkane. Its clear, oily consistency shows up anywhere from laboratories to manufacturing workbenches. Some producers use it as a fuel additive, some folks see it pop up in cleaning mixtures, and others find it in test tubes during chemical research. Having seen it on chemical bottles and handling material safety data sheets, I always got the sense it doesn’t make headlines like benzene or toluene. Still, any chemical showing up in industrial settings deserves unbiased scrutiny.

Toxicity: Where Does It Stand?

Out in the real world, nobody takes a swig of straight tridecane—there’s not much chance of finding it in your kitchen. According to the U.S. National Library of Medicine and the European Chemicals Agency, n-tridecane is considered to have low acute toxicity. Most safety data sheets label it with phrases like “harmful if swallowed” or “may cause skin irritation,” which is fairly standard for many hydrocarbons. Inhaling high concentrations can irritate the nose, throat, and lungs. Overexposure, like in most solvents, could cause drowsiness or headaches. Few folks realize that symptoms only appear after longer or stronger exposures—laboratory workers in reasonable conditions typically aren’t reporting trouble.

Long-term Exposure and Environmental Impact

My own journey through labs and workshops taught me early: chemicals with a faint odor and oily feel tend to stick around more than you’d like. N-tridecane isn’t classed as carcinogenic or mutagenic by major medical authorities. The risk of chronic health problems stays low under reasonable use. The bigger worry, though, lies in spills or leaks. This compound breaks down slowly outdoors, especially in soil, as it takes time for sunlight or microbes to finish the job. Fish and aquatic bugs can’t handle tridecane in large amounts. Dumping or carelessness could damage sensitive river and lake life long after everybody packed up and left.

Safety: Practices and Precautions

Working with tridecane calls for gloves and splash goggles—the sort you’d use with any low-grade solvent. Fume hoods or good airflow hold down the risk from breathing vapors. I’ve seen small spills on the lab table cleaned up with absorbent pads, but flushing it down the sink or tossing soaked rags into regular trash spells bad news for water systems. Wearing the right gear, proper storage with sealed containers, and clear labeling all make a difference. From high school chemistry sets to the research bench, day-to-day practices matter more than the specific chemical.

Heading in the Right Direction

Even chemicals with a reputation for “low hazard” need attention. Risk isn’t always about the strongest poison. It’s about how real people handle real materials: education, adequate ventilation, and spill plans. Industry groups could encourage better container management and step up wastewater treatment, especially in places near lakes or streams. Regulatory agencies already watch for solvent emissions and spills. Clean habits in storage, awareness of what heads down the drain, and clear rules for disposal protect both workers and nearby wildlife. Chemicals don’t have to be scary, but they demand respect and common sense.

How should N-Tridecane be stored?

Fire Risk Comes First

N-Tridecane won’t explode at the drop of a hat, but this liquid burns just like other hydrocarbons. I’ve seen careless handling lead to smoke and panic, even outside of large chemical plants. Flammable vapors rise off this stuff at room temperature, and those vapors catch easily—think of how quickly gasoline starts a fire. For this reason, contact with sparks or open flames should never happen nearby. People working with N-Tridecane wouldn’t want to underestimate it, even if it looks innocuous.

A metal drum with a tight lid fits the job best. Polyethylene containers also work, as long as they close securely and never see unintended leaks. I prefer steel for extra peace of mind in warm climates. Store drums away from heat sources, and give each its own space rather than stacking them like soup cans. If a spill does occur, material left pooled on the floor poses a real slipping hazard, so absorbent pads and clean-up kits should sit nearby.

Choose a Cool, Ventilated Storage Area

Common sense says avoid hot storage rooms. Most chemical guides set the upper temperature at about 25°C (77°F)—basically, a well-ventilated space just under typical indoor comfort. Sunlight shouldn’t hit N-Tridecane containers directly; constant heat speeds up vapor release and ups the fire risk. Sun-warmed containers also expand, and I’ve seen gaskets fail from this repeated stress.

Good air flow pushes vapors out. Stuffy sheds or cupboards make it tough for evaporated solvent to escape. Installing an exhaust fan and putting storage near open bays cuts down on vapor build-up. Fumes may not bother folks today, but long-term exposure sometimes causes headaches or worse. The health risks don’t disappear just because it's a relatively low-toxicity hydrocarbon.

Avoid Mixing With Oxidizers and Acids

One lesson often learned the hard way: some chemicals bring out the worst in N-Tridecane. Storing it alongside strong oxidizers or concentrated acids asks for trouble—those can react harshly, even without much encouragement. I recall a time a careless worker stacked peroxide near another alkane, leading to a near-miss. A shelf label isn’t enough. Smart storage means using sturdy separators or, better yet, separate rooms for reactive groups.

Label Every Container

Experience says mystery drums cause headaches down the line. Proper labels spare trouble, both for safety and compliance. Every can, drum, or jug of N-Tridecane ought to show the product name, content details, and date it arrived. Sometimes I’ve opened storerooms and found faded markers or covered-up labels that made identification slow. Clear, chemical-resistant labels stay readable even after handling or minor spills.

Personal Protection Makes a Difference

Handling N-Tridecane isn’t rocket science, but gloves, chem splash goggles, and proper clothing should be standard practice—especially during transfers. People tend to skip eye protection for routine work, but I’ve seen solvents splash unexpectedly more often than most admit. Once a guy ended up washing his eyes for several minutes after dodging a minor spill. A face shield never hurts during bulk transfer. Even the minor skin irritation from prolonged contact isn’t worth the risk.

For spills, use absorbents and dispose of waste through approved chemical disposals. Pouring it down the drain or letting it evaporate in the open is illegal and simply reckless, given its environmental impact.

Putting Safety Above Speed

The main point—N-Tridecane’s low drama doesn’t mean shortcuts. Fires, confusion, and unnecessary exposure can be kept at bay through good old planning and attention. Old habits shape outcomes, and habits that keep storage cool, segregated, and well-labeled will serve everyone well. Safe storage lets workers focus on their main jobs and keeps regulators satisfied—good outcomes for anyone dealing with this chemical.

What is the chemical formula of N-Tridecane?

What Chemistry Looks Like Beyond the Textbook

Take a look at N-Tridecane: its chemical formula, C13H28, might not be the headline material, but this straight-chain alkane stands as a good example of what basic organic molecules can do once they leave the classroom. Understanding its formula means more than just memorizing symbols—it shows the real backbone of molecules we encounter in fuels, lubricants, and even the air around us.

Why C13H28 Matters Off the Page

N-Tridecane packs thirteen carbon atoms and twenty-eight hydrogens. This simple ratio signals a stable, non-polar structure recognized in the hydrocarbon family. Refineries use compounds with similar setups, not simply because of tradition, but due to how predictably they behave under heat or pressure. Growing up in a family where fuel lines and engines often sat halfway across the living room on weekends, I saw how alkanes like tridecane shape the world.

Stand next to a fuel truck or watch chemists at work in a lab; conversations touch on boiling points, safety, and reliable burning. C13H28 boils around 234°C. That mid-range volatility helps keep engines running smooth, and it means folks handling solvents and fuels don’t worry about surprise flashes. Substance like tridecane deliver baseline confidence in both process safety and end use.

Science at Work through Everyday Problems

I remember helping an uncle with old lawn mowers that coughed and spluttered, just because someone slipped in the wrong grade of solvent during cleaning. Straight-chain alkanes, like tridecane, rarely cause such trouble. Part of that is down to the chemical formula—it holds no double or triple bonds, so combustion and cleaning rarely produce strange byproducts. That’s not only easier on the machines but keeps fumes from clogging the air in small garages.

The Environmental Protection Agency watches these molecules closely. Spills and releases matter, since they break down slowly. The formula C13H28 doesn’t just point to size, but signals persistence. Experience working in industrial settings taught me how environmental folks want fewer surprises—molecules like tridecane play by clear rules. Monitoring and cleanup depend on accuracy. Knowing the formula allows rapid testing in the field, supporting cleanups before a spill grows.

Toward Better Solutions in the Alkane World

So, a label reading C13H28 means more than a high school chemistry answer. For fuel blending, labs search for hydrocarbons that burn steadily, store well, and resist corrosion. Alkanes like tridecane fit the bill. But the conversation runs deeper. Industry and environmental leaders need greener pathways—ways to produce, use, and dispose of these hydrocarbons without burdening health or habitat.

Better labeling, detailed recordkeeping, and targeted cleanup supplies depend on this attention to formula. Research into biodegradable alternatives or recycling approaches often use molecules like tridecane as benchmarks. The chemical formula stays at the core of these choices, guiding safety and sustainability.

Taking Chemistry from Paper Into Practice

Understanding the formula for N-Tridecane doesn’t close the book on chemistry. It helps foster safer handling, shapes smarter industrial choices, and ensures everyone from the weekend mechanic to the refinery engineer knows exactly what they’re dealing with. Knowledge like this shapes how we store, transport, and even clean up after common chemicals every day. Keeping that awareness front and center makes our industries and our home projects just a little bit safer.
