Oxidation of unsaturated aldehydes to unsaturated acids

An improved process for catalytically oxidizing alpha-beta unsaturated aliphatic aldehydes in the vapor phase with molecular oxygen to produce alpha-beta unsaturated carboxylic acids using a catalyst composition which has been thermally activated in the presence of ammonia, and which comprises the e...
