Frequently Asked Questions
How is Chloromethane stored and handled?
Operation precautions:
Strictly sealed, provide sufficient local exhaust and comprehensive ventilation. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear filter gas masks (half masks), chemical safety goggles, breathable anti-virus clothing, and chemical-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent gas leakage into the workplace air. When transporting, load and unload lightly to prevent damage to cylinders and accessories. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment.
Storage precautions:
Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. Storage temperature should not exceed 30 ℃. It should be kept away from oxidizer, do not store together. Explosion-proof lighting and ventilation facilities are adopted. Prohibit the use of mechanical equipment and tools that are prone to sparks.

What is Chloromethane used for?
This product is used in the production of methyl chlorosilane, tetramethyl lead, methyl cellulose, etc., a small amount is used in the production of quaternary ammonium compounds, pesticides, and is used as a solvent in the production of isobutylene rubber.
This product is an important raw material for organic synthesis. Mainly used to produce organosilicon compound - methyl chlorosilane, and methyl cellulose. It is also widely used as a solvent, extractant, propellant, refrigerant, local anesthetic, methylation reagent, and used in the production of pesticides, medicines, spices, etc. About 80% of the methyl chloride produced in the world is used to produce methyl chlorosilane and tetramethyl lead, but since the antiknock compounds in gasoline are gradually being replaced by unleaded substances, the consumption of tetramethyl lead is gradually decreasing.
