Ⅰ.Characteristicsand Applications
Dimethyl carbonate, with molecular formulaC4H8O3, structuralformula, is a colorless andtransparent liquid with melting point4℃and boilingpoint90.3℃, can be mixed with organicsolvents such as alcohols, ketones, esters etc in any proportionbut slightly soluble in water.
As awidely-used chemical raw material, dimethyl carbonate is a kind ofoutstanding methylating reagent, carbonylating reagent, and anideal substitute for phosgene, dimethyl sulfate and methylchloroformate, and widely used for synthesizing diphenyl carbonate,isocaynate, allyl diethylene glycol carbonate and carbamatespesticide. Dimethyl carbonate can also be used in such industries,such as special non-pollution paint, ink, coating andpharmaceuticals, solvent of lithium battery electrolyte in batteryindustry, fine oxygenous additive of alcohol and ethergasoline.
