    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 average pore diameter of from 3.5 to 50 nm, 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.

    摘要: Provided is a method for continuously producing a cyclic carbonate, by which generation of a glycol in a reaction for synthesizing a cyclic carbonate is suppressed, and a cyclic carbonate having a high purity can be efficiently obtained even by simple purification. A method for continuously producing a cyclic carbonate, including filling a catalyst in a fixed-bed tube reactor, and continuously feeding carbon dioxide and an epoxide to the fixed-bed tube reactor to thereby bringing the carbon dioxide and the epoxide into contact with the catalyst, while continuously withdrawing the reaction liquid in the fixed-bed tube reactor, wherein the method includes a pre-treatment step in which a pre-treatment liquid containing a cyclic carbonate is brought into contact with the catalyst before feeding the carbon dioxide and the epoxide to the fixed-bed tube reactor, and the generated glycol is removed out of the system.
