PROCESS FOR PURIFYING DIALKYL CARBONATE

摘要

The invention relates to a process for purifying dialkyl carbonate by membrane separation, wherein a membrane having an average pore size of from 0 to 10 nm is used. The dialkyl carbonates cover both acyclic dialkyl carbonates, such as dimethyl carbonate and diethyl carbonate, and alkylene carbonates wherein the alkyl groups are linked together to form a ring, such as ethylene carbonate.
