PROCESS FOR PRODUCTION OF CYCLIC CARBONATES

WIPO Patent Application WO/2005/085224

A1

The invention provides a process for the production of cyclic carbonates which is applicable to various fields including organic solvents, finishing agents for synthetic fibers, raw materials of drugs, solvents for the electrolytic solution for lithium batteries, and intermediates for the synthesis of alkylene glycols or dialkyl carbonates and advantageous in respect of the service life of a catalyst or the equipment. A process for the production of cyclic carbonates which comprises the step of reacting an epoxide with carbon dioxide, wherein the reaction is conducted in the presence of both at least one element selected from the group consisting of alkali metal elements and alkaline earth metal elements and a metal oxide; and cyclic carbonates obtained by the process which have halogen concentrations of 1ppm or below.
