Procedure

Subsequently, the resulting mixed gas (a raw material gas) is passed through a dehydration catalyst to decompose part of t-butanol into isobutylene and water by dehydration reaction and then supplied; otherwise the resulting mixed gas is not sent through said dehydration catalyst and directly supplied; to an oxidation catalyst layer maintained at a predetermined temperature to obtain methacrolein and/or methacrylic acid by catalytic gas phase oxidation reaction.
