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 base catalyst, obtained by formulating at least one alkali metal compound selected from the group consisting of alkoxides, hydroxides and oxides of alkali metals and an alkaline-earth metal oxide in a ratio of &ldquo;the weight of alkaline metal compound/the weight of alkaline-earth metal oxide&rdquo;&equals;0.005 to 1, is used in a reaction of an aldehyde to produce a glycol monoester, thereby providing a base catalyst with an improved efficiency which can be applied to aldol reaction or the like and which has high activity to give target product in a high selectivity.
