Abstract
A process for producing acrylic acid from propane and oxygen gas through a vapor-phase catalytic oxidation reaction, said process comprising conducting the reaction using as a catalyst a metal oxide containing metallic elements Mo, V, Sb, and A (provided that A is at least one element selected from the group consisting of Nb, Ta, Sn, W, Ti, Ni, Fe, Cr, and Co). The metal oxide is prepared by a process including specific steps (1) and (2). The metal oxide may be supported on a compound containing specific elements.
