Abstract
In a process for oxidation of methacrolein to methacrylic acid the carbon monoxide present in the recycle gas can be selectively oxidized to carbon dioxide with substantially no oxidation of the methacrolein content. A preferred catalyst for such an oxidation is a crystalline alumino silicate having pores of about 4-5 angstroms diameter and containing within the pores at least one metal or compound of the noble metal group, particularly platinum.
