<p>A heteroaromatic nitrile is prepared in high conversion and yield by catalytically reacting an alkyl-substituted heteroaromatic compound with molecular oxygen and ammonia in the presence of a catalyst having the following composition: Mo(P)x(A)y(B)z(O)w (I) wherein x, y, z and w represent atomic ratios of phosphorus, an element A defined below, an element B defined below and oxygen to molybdenum, respectively and (i) x and z are both 0 (zero), y is from 0.1 to 5, and A is at least one element selected from the group con sisting of cerium or tungsten, or (ii) x is from 0.1 to 7, y is from 0 to 5, z is from 0 to 5, A is at least one element selected from the group consisting of cerium, manganese and tungsten, and B is at least one element selected from the group consisting of thallium, titanium, niobium and aluminum, or (iii) x is from 0.5 to 7, y is from 0 to 5, z is from 0.01 to 2, A is at least one element selected from the group consisting of cerium, manganese and tungsten, and B is vanadium, and w is defined from the valencies of molybdenum, phosphorus, the element A, the element B and the values x, y and z.</p> |
