Title:
PRODUCTION OF CHAIN CARBONATE
Document Type and Number:
Japanese Patent JPH09118652
Kind Code:
A
Abstract:
To obtain a chain carbonate useful as a synthetic raw material for electrolyte, etc., by transesterification without using a chemical substance poisonous to human bodies by using a specific catalyst.
Transesterification of a carbonate such as dimethyl carbonate with a monohydric alcohol such as ethyl alcohol is carried out in the presence of a catalyst comprising at least one kind of a metal oxide selected from III B group elements such as yttrium and samarium to provide the objective chain carbonate such as methylethyl carbonate or diethyl carbonate.
