Diethylene Glycol
Diethylene Glycol (DEG), also known as Dihyroxy diethyl ether, is a colorless, virtually odorless, viscous liquid. It distinguishes itself with a higher boiling point, viscosity, and specific gravity compared to MEG, showcasing exceptional solvent power, remarkable hygroscopicity, and minimal vapor loss. DEG, a straight-chain dihydric alcohol terminated with hydroxyl groups at both ends, presents as a clear, water-white, practically odorless, and hygroscopic liquid at room temperature, with a boiling point of 245°C. It demonstrates water solubility and can dissolve in numerous organic solvents. DEG is produced through the partial hydrolysis of ethylene oxide and is obtained as a co-product in ethylene glycol production.

Moreover, it can enhance the performance of lubricating oils and reduce frictional losses as a lubricant. Diethylene glycol also acts as a plasticizer for plastics, improving their flexibility and ductility, and finds applications in the pharmaceutical industry as a solvent or diluent for drugs. In cosmetics, such as skincare products, perfumes, and lipsticks, Diethylene glycol is employed as a solvent and diluent.

How is diethylene glycol made?
Diethylene glycol is typically produced through the partial hydrolysis of ethylene oxide. This reaction results in the formation of monoethylene glycol (MEG) and diethylene glycol as co-products. Diethylene glycol can then be separated from the reaction mixture through processes such as distillation or fractional crystallization. Additionally, diethylene glycol can also be obtained as a byproduct in the production of ethylene glycol.

Is diethylene glycol hazardous ?
Diethylene glycol can be hazardous if not handled properly. It is classified as a toxic substance and can pose health risks if ingested, inhaled, or absorbed through the skin. Ingestion of diethylene glycol can lead to symptoms such as nausea, vomiting, abdominal pain, and in severe cases, kidney and liver damage. Inhalation of its vapors can irritate the respiratory tract and cause symptoms such as coughing and shortness of breath. Skin contact with diethylene glycol may result in irritation or allergic reactions.
Moreover, diethylene glycol is flammable and can pose fire hazards under certain conditions. Therefore, appropriate safety measures should be taken when handling diethylene glycol, including wearing protective equipment, ensuring adequate ventilation, and implementing proper storage and disposal procedures.

What are the differences between Diethylene Glycol and Ethylene Glycol
