Abstract

PURPOSE: The oxidation reaction of an α,β-unsaturated aldehyde and an alcohol with molecular oxygen is conducted in the presence of a specific catalyst to produce on one step an α,β-unsaturated carboxylic ester in high yield.
CONSTITUTION: The oxidation reaction of an α,β-unsaturated aldehyde of formula I (R1-3 are H, alkyl, aryl) such as methacrolein and an alcohol of formula: R4- OH (R4 is 1W10C alkyl) such as methanol with molecular oxygen is conducted in the presence of a catalyst consisting of (a) at least one from Pd and its compounds, (b) at least one from alkaline earth metals, Zn, Cd and oxides, hydroxides and sulfates of these metals and a polymerization inhibitor at 10W300°C and 1W40 atmospheric pressure to produce the objective compound of formula II such as methyl methacrylate. Pd is preferably supported on carbon or alumina.
EFFECT: Operations of recovery and purification can be done with extremely easiness and an inexpensive material can be used for reaction equipments.
