Dimethyl Carbonate

Dimethyl carbonate is briefly referred to as DMC,characteristics of colorless transparent liquid, irritating odor. Properties is an important organic synthesis intermediates, molecular structure containing carbonyl, methyl and methoxy functional groups, with a variety of reaction properties, in the production of safe and convenient, characteristics of less pollution and easy transportation. Used in chemical synthesis of methylating agent and carbonylating agent, widely used in food antioxidants, plant protection agents and other fields.
