Abstract

PURPOSE: To obtain the titled compound in excellent selectivity, productivity and catalyst life, by oxidizing isobutane in one step using a Mo-containing heteropolyacid having P or As as center atom or a salt of said polyacid as a catalyst in a state of high degree of reduction.
CONSTITUTION: Methacrylic acid and/or methacrolein can be produced by oxidizing a gas containing isobutane in the presence or absence of oxygen at 250W450°C using a catalyst comprising a Mo-containing heteropolyacid having P or As as center atom or its salt (e.g. phosphomolybdic acid, arsenomolybdic acid, etc.) at a reduction degree corresponding to 1W6 electrons, especially 2W4 electrons per one molecule of the heteropolyacid. Especially methacrylic acid can be produced from isobutane in high selectivity. The combined selectivity of methacrylic acid and methacrolein exceeds 50%.
