Title:
METHOD FOR PRODUCING FOUR-MEMBERED RING LACTONE AND HETEROGENEOUS CATALYST
Document Type and Number:
WIPO Patent Application WO/2017/170808
Kind Code:
A1
Abstract:
To provide a technique for producing a four-membered ring lactone more efficiently with higher yield by means of a carbonylation reaction of an epoxide using a heterogeneous catalyst that is able to be handled in air and is easily separated from the reaction product. A method for producing a four-membered ring lactone by means of a carbonylation reaction of an epoxide, which comprises a step wherein the epoxide and carbon monoxide are reacted with each other in the presence of (A) a heterogeneous catalyst in which an oxide of one or more metals selected from among group 5 to group 10 transition metals is used as a carrier, and the carrier is loaded with one or more substances selected from among group 10 transition metals, group 11 transition metals and oxides of these transition metals (provided that the metals in the loaded substances are different from the metals in the metal oxide used as the carrier), (B) a metal Lewis acid, and (C) a Lewis base that contains an atom selected from among an oxygen atom and a nitrogen atom in each molecule.
