    摘要: Provided are : a method for easily producing a heterogeneous catalyst having excellent catalytic activity at a low cost, said heterogeneous catalyst being used for the purpose of synthesizing a cyclic carbonate by subjecting to a reaction an epoxide and carbon dioxide; a catalyst which is obtained by this production method; and a method for synthesizing a cyclic carbonate with use of this 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 subjecting to a reaction a silane compound having a haloalkyl group or a haloaryl group and a silica gel having an amount of adsorbed water of 1% by mass or less and
    (b) a step of obtaining a catalyst for cyclic carbonate synthesis, by subjecting to a reaction the catalyst precursor obtained in step (a) and a tertiary phosphine, in which the molar ratio of the halogen content to the phosphorus content, namely [halogen]/[phosphorus] is from 0.8 to 1.6.
