Title:
PRODUCTION OF LACTONES
Document Type and Number:
Japanese Patent JP3194799
Kind Code:
B2
Abstract:
PURPOSE: To produce lactones, especially γ-butyrolactone in high selectivity by one-stage hydrogenation reaction under a mild condition even in the case of a saturated or unsaturated dicarboxylic acid derivative as a raw material.
CONSTITUTION: In hydrogenating a saturated or unsaturated dicarboxylic acid derivative, a catalyst comprising at least one metal selected from elements of group VIII of the periodic table or the metal and at least one element selected from elements of the group IVa, VIB or VIIb of the periodic table is used and the reaction is carried out in the presence of an alkali metal salt to produce lactones.
