ABSTRACT:
An improvement in the process for producing acrylic or methacrylic acid by the vapor phase catalytic oxidation of a system containing acrolein or methacrolein, respectively, is provided. The improvement resides in the employment, in such process, of a novel catalyst prepared by admixing with a solution of the catalytic components an organic substance, for example from the group of organic acids, alcohols, amines, esters and quinones, drying the admixture and subsequently calcining the admixture at a temperature in the range of 330.degree. to 430.degree.C to form the novel catalyst.
