Dimethyl Carbonate Usage:
1. A new low toxic solvent can replace toluene, xylene, ethyl acetate, butyl acetate, acetone or butanone in the paint and adhesive industry. It is an environmental friendly green chemical product
2. Good methylating agent, carbonylating agent, hydroxymethylating agent and methoxylating agent are widely used chemical raw materials
3. Phosgene, dimethyl sulfate, methyl chloroformate and other highly toxic chemicals are considered substitutes
4. Synthesis of polycarbonate, diphenyl carbonate, isocyanate, etc
5. In medicine, it is used to synthesize anti infective drugs, antipyretic and analgesic drugs, vitamins and central nervous system drugs
6. Pesticides are mainly used to produce methyl isocyanate, and then some carbamate drugs and pesticides (anisole)
7. Gasoline additives, lithium battery electrolyte, etc
Dimethyl Carbonate transportation information:
UN: 1161 Class: 3 PG: Ⅱ
HS Code: 2920900090
Hazardous Characteristics
Flammable, flammable in case of open fire and high heat. In the fire scene, heated containers have explosion risk.
Harmful combustion products
Carbon monoxide, carbon dioxide.
Fire extinguishing method
Sand. Foam, dry powder, carbon dioxide.
Emergency treatment
Evacuate the personnel from the leakage contaminated area to the safe area quickly, isolate them and strictly restrict their access. Cut off the fire source. It is recommended that emergency treatment personnel wear self-contained positive pressure respirators and anti-static work clothes. Do not touch the leakage directly. Cut off the source of leakage as far as possible. Prevent from flowing into restricted spaces such as sewers and flood discharge ditches. Small leakage: absorb with sand, vermiculite or other inert materials. Collect and transport to an open place for burial, evaporation or incineration. Massive leakage: build a dike or dig a pit for collection. Cover with foam to reduce steam disaster. Transfer to tank car or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.
Precautions for operation
Airtight operation and enhanced ventilation. Operators must receive special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter gas masks (half masks), chemical safety glasses, anti-static work clothes and rubber oil resistant gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation system and equipment. Prevent steam from leaking into the air of the workplace. Avoid contact with oxidants, reductants and acids. Handle with care to prevent damage to the package and container. Fire fighting equipment and leakage emergency treatment equipment of corresponding varieties and quantities shall be provided. Emptied containers may contain harmful substances.
Storage precautions
Store in a cool, dry and well ventilated non combustible warehouse. Keep away from fire and heat source. The storage temperature should not exceed 10 ℃. Keep containers sealed. It shall be stored separately from oxidants, reductants, acids, etc. and mixed storage shall not be allowed. Explosion proof lighting and ventilation facilities shall be adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area shall be equipped with leakage emergency treatment equipment and appropriate receiving materials.
