US 12,172,949 B2 · Method for producing alcohol

Abstract

The present invention provides a method for selectively producing an alcohol by efficiently hydrogenating a lactone. The present invention is a method for producing an alcohol, the method including hydrogenating a substrate lactone represented by Formula (1), in the presence of a catalyst described below, to produce an alcohol that is represented by Formula (2). In the formulae, R represents a divalent hydrocarbon group which may have a hydroxyl group. The catalyst comprises: metal species including M1 and M2; and a support supporting the metal species, and wherein M1 is rhodium, platinum, ruthenium, iridium, or palladium; M2 is tin, vanadium, molybdenum, tungsten, or rhenium; and the support is hydroxyapatite, fluorapatite, hydrotalcite, or ZrO2.

Claims11

Dependent claims

A catalyst comprising:

metal species including M1 and M2 in a ratio of from 0.3 to 0.8 mol of M2 per 1 mol of M1;
and
a support supporting the metal species,
wherein:
M1 is platinum;
M2 is molybdenum;
and
the support ZrO2,
wherein the catalyst is a catalyst prepared using a sequential impregnation method in which M2 is first supported on the support and then M1 is supported on the support, and
wherein the catalyst is used to hydrogenate a lactone to form a corresponding alcohol.
