PROBLEM TO BE SOLVED: To obtain the subject compound in high yield by catalytically oxidizing a raw material which is propylene, tert-butanol, etc., with molecular oxygen in a vapor phase by using a specific catalyst. SOLUTION: (A) A raw material which is propylene, isobutylene, tert-butanol or methyl t-butyl ether is catalytically oxidized in a vapor phase with (B) molecular oxygen in the presence of a catalyst having a composition of the formula (X is nickel, cobalt, magnesium, manganese, chromium or zinc; Y is cerium, tungsten, lanthanum, silver or tin; Z is sodium, potassium, rubidium, cesium or thallium; (a) to (j) are each an atomic ratio of each element and when (a) is 12, 0.5<=b<=5, 0.5<=c<=8, 1<=d<=12, 0.5<=e<=8, 1<=f<=30, 0<=g<=8, 0<=h<=5 and 0.01<=i<=1 and (j) is the number of oxygen atoms required for satisfying the valence of each component). Preferably, the reaction is carried out by using the components A and B in the molecular ratio of the components A:B of 1:(0.5-3). |
