Method for producing catalyst for cyclic carbonate synthesis

Abstract

The present invention provides a method for easily and inexpensively producing a heterogeneous catalyst used to synthesize a cyclic carbonate by reacting an epoxide with carbon dioxide and having excellent catalyst activity; a catalyst obtained using said manufacturing method; and a method for synthesizing a cyclic carbonate using said catalyst. A method for producing a catalyst that is used for the purpose of synthesizing a cyclic carbonate by subjecting to a reaction an epoxide with carbon dioxide, said method comprising the following steps (a) and (b): (a) a step of obtaining a catalyst precursor having a haloalkyl group or a haloaryl group by reacting a silane compound with a silica gel in the presence of xylene, the silane compound having a haloalkyl group or a haloaryl group and (b) a step of obtaining a catalyst for synthesizing a cyclic carbonate by reacting the catalyst precursor obtained in step (a) with a tertiary phosphine.
