Abstract:
1. A method for producing an unsaturated oxygen-containing compound by the vapor-phase catalytic oxidation of an alkane, comprising subjecting an alkane to vapor-phase catalytic oxidation in the presence of a catalyst, wherein at least 50% of said catalyst has an appearance of needle crystal by observation by an electron microscope and having a specific surface area of 2-50 m 2 /g, which catalyst is represented by general Formula (1) as shown below, wherein, X represents at least one element selected from the group consisting of Sb and Te; Y represents at least one element selected from the group consisting of Nb, W and Zr; a, b, c, d and e represent atomic ratios of their respective elements, with 0<a<0.7, 0<b<0.3, 0<c<0.7, 0.1≦d<0.3 and e is a number determined by the oxidation states of the other elements than oxygen.
