Abstract

PURPOSE: To prepare methacrylic acid in high selectivity and high yield by the gas-phase oxidation of methacrolein with molecular oxygen in the presence of catalysts comprising at least five kinds of elements selected from Pd, P, Sb, O, etc., which are stable to heat and have a long life.
