Product Applications

It is used as solvent and also for organic synthesis; It is mainly used as solvent for cellulose ether, nitrocellulose, natural and synthetic resin, and also used for synthesis of phenobarbital, deltamethrin, etc. Diethyl carbonate is an important intermediate for organic synthesis. Mainly used as nitrated cellulose, cellulose ether, synthetic resin..

Production method

Anhydrous ethanol reacts with phosgene to form ethyl chloroformate, and then continues to react with ethanol to form diethyl carbonate. Then, the finished product is obtained by washing and distilling. Raw material consumption quota: ethanol 1450kg/t; Phosgene 2250kg/t.
