Title:
炭酸エステルの製造方法
Document Type and Number:
Japanese Patent JP4470725
Kind Code:
B2
Abstract:

To provide a method for producing carbonic ester by a liquid phase transesterification reaction between dialkyl carbonate and aliphatic alcohol wherein the target product of industrially suitable quality can easily be separated by distillation in no need of complicated operations, for example, the neutralization of the catalyst after the reaction, the removal of the catalyst and can produce the target compound through the high-speed reaction rate.

Dialkyl carbonate and aliphatic alcohol are subjected to a transesterification reaction in the presence of a temperature-sensitive catalyst under elevated-temperature liquid phase or supercritical phase to form the target carbonic ester and the reaction mixture is fed to the distillation equipment without the operation of catalyst removal.
