A catalyst for ester production which comprises zirconium oxide, copper, and at least one oxide selected from the group consisting of zinc oxide, chromium oxide, aluminum oxide and silicon oxide, and is obtainable by reducing with hydrogen a catalyst precursor prepared by the reaction of a salt containing at least one of metals constituting the oxides, a zirconium salt and a copper salt with an alkali hydroxide; and a process for producing an ester which comprises bringing either an alcohol or an alcohol and an aldehyde into contact with this catalyst in a gas phase.

Catalyst for ester production and process for producing ester

A catalyst which causes no occurrence of waste water due to neutralization, water-washing, etc. and can yield the objective product with a high activity and a superior selectivity is provided, and when a specified barium-supporting calcium oxide or a composite oxide of barium oxide with calcium oxide is used as catalyst, such a catalyst is applicable, for example, to a production of a carbonyl compound derivative from a carbonyl compound.
