Document Type and Number:
Japanese Patent JPH07121925
Kind Code:
B2
Abstract:
A method for producing a lactone by hydrogenating a dicarboxylic acid, a dicarboxylic acid anhydride and/or a dicarboxylic acid ester in the presence of a catalyst, wherein the hydrogenation reaction is conducted in the liquid phase in the presence of (1) ruthenium, (2) an organic phosphine and (3) a compound of a metal selected from the group consisting of Groups IVA, VA and IIIB in the Periodic Table. According to the present invention, for the production of a lactone by hydrogenating a dicarboxylic acid, a dicarboxylic acid anhydride and/or a dicarboxylic ester, the reaction is conducted in a homogeneous liquid phase reaction by using the ruthenium, organic phosphine and compound of a metal selected from the group consisting of Groups IVA, VA and IIIB, of the present invention as the catalyst, whereby the desired lactone product can be obtained at high selectivity under a mild condition as compared with the conventional methods.
