Summary:PURPOSE:To improve catalytic activity and selectivity by consisting a titled catalyst of caralytic active materials such as Mo, V and W and forming the same into an annular catalyst having a specific outside diameter, a length which is 0.5-2.0 times the outside diameter and through-holes of specific inside diameters. CONSTITUTION:The catalytic active material expressed by the formulaI(A is the element selected from tungsten and niobium, B is the element selected from iron, copper, bismuth, chromium and antimony, C is the element selected from alkali mtals and alkaline earth metals, D is the element selected from silicon, aluminum and titanium; a, b, c, d, e, f, x denote the atom numbers of the respective elements) is molded to the annular state having 3.0-10.0mm. outside diameter, the length which is 0.5-2.0 times the outside diameter, and through- holes having inside diameter of 0.1-0.7-times the outside diameter in the longitudinal axial direction thereof.
