Abstract:
1. A solid catalyst comprising a core and shell catalytic phase for use in the manufacturing of a nitrile compound, wherein the solid catalyst is expressed by the following formula (1): wherein: A is one or more elements selected from the group consisting of boron, phosphorus, molybdenum and arsenic; B is one or more elements having the atomic valence of 1-2 selected from the group consisting of potassium, cesium, nickel, cobalt, manganese and magnesium; C is one or more elements having the atomic valence of 3-6 selected from the group consisting of iron, chromium, cerium, niobium, vanadium and tellurium; D is one or more elements having the atomic valence of 3-6 selected from the group consisting of aluminum, cerium and chromium; E is one or more elements having the atomic valence of 1-2 selected from the group consisting of cobalt, manganese, magnesium, calcium, copper and cesium; when m is 1, n is 0.001-3, a is 0.001-3, b is 0-3, c is 0-1, d is 0-3, e is 0-3, f is 0.01-5, g is 0.01-5, and z is 0-90; and x and y are numbers such that the valence requirements of the other elements for oxygen in the core and shell catalytic phase, respectively are satisfied.
