Application
1. Pharmacy: DMC is mainly used for the synthesis of anti infectious drugs, antipyretic analgesic drugs, vitamins, central nervous system drugs.
2. Pesticide: DMC is mainly used to produce methyl isocyanate and further to produce amino formic acid medicine, etc. It can be used to produce isocyanate, allyl diethylene glycol carbonate instead of extremely toxic phosgene carbonylation agent.
3. Solvent: DMC is an excellent environment solvent and be widely used to coating, printing ink, adhesive and etc..
