METHOD FOR PRODUCING CATALYST FOR CYCLIC CARBONATE SYNTHESIS
Document Type and Number:
WIPO Patent Application WO/2014/175261
Kind Code:
A1
Abstract:
Provided are: a method for easily producing a heterogeneous catalyst having excellent catalytic activity at low cost, said heterogeneous catalyst being used for the purpose of synthesizing a cyclic carbonate by reacting an epoxide and carbon dioxide with each other; 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 reacting an epoxide and carbon dioxide with each other, said method comprising the following steps (a) and (b).
(a) a step wherein a silane compound having a haloalkyl group or a haloaryl group and a silica gel having an average pore diameter within the range of 3.5-50 nm are reacted with each other, thereby obtaining a catalyst precursor having a haloalkyl group or a haloaryl group
(b) a step wherein the catalyst precursor obtained in step (a) and a tertiary phosphine are reacted with each other, thereby obtaining a catalyst for cyclic carbonate synthesis, in which the molar ratio of the halogen content to the phosphorus content, namely [halogen]/[phosphorus] is 0.8-1.6.
