This invention concerns a promoted catalyst system for making one or more alkanols from synthesis gas. The catalyst system contains a ruthenium compound and a halogen promoter dispersed in a low-melting tetraorganophosphonium salt. The halogen promoter is a compound capable of generating HX (where X═Cl, Br, or I) under reaction conditions. The invention also concerns a process for selectively preparing one or more alkanols from synthesis gas using the promoted catalyst system.

Provided is a method for producing a cyclic carbonate obtained by reacting epoxide and carbon dioxide, the method being capable of efficiently producing a cyclic carbonate at a high conversion rate and a high yield, in which degradation of the catalyst over time is suppressed and catalytic activity hardly decreases.
A method for producing a cyclic carbonate by reacting epoxide and carbon dioxide in the presence of a quaternary onium salt selected from the group consisting of a quaternary ammonium salt having a halogenated anion as a counter ion and a quaternary phosphonium salt having a halogenated anion as a counter ion, or in the presence of a solid catalyst obtained by immobilizing the quaternary onium salt onto a carrier, wherein an organohalogen compound containing at least one halogen atom in one molecule is added to the reaction system.

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.
