PRODUCTION OF CATALYST FOR HYDROGENATION REACTION OF ALIPHATIC ALKYL ESTER

Title:

PRODUCTION OF CATALYST FOR HYDROGENATION REACTION OF ALIPHATIC ALKYL ESTER

Document Type and Number:

Japanese Patent JPH08108072

Kind Code:

A

Abstract:

PURPOSE: To obtain a Cu-Mn-Al catalyst having high activity, producing a small amt. of a by-product and easily separable from a product by filtration.

CONSTITUTION: When a catalyst contg. copper oxide, aluminum oxide and manganese oxide as constituent components is prepd. by coprecipitation, an aq. soln. of metallic salts and an alkali metallic compd. are continuously and simultaneously added to heated water under stirring at a constant pH. In this method, alumina hydrate is previously added to at least one of the aq. soln. and the heated water.
