Selectivity of the catalyst comprising K, Ni, Co, Fe, Bi, Mo, and P oxides on silica gel was increased and its prepn. by pptn. from solns. followed by drying and calcining at 550-650° was simplified by combining the ammonium paramolybdate soln. with H3PO4, adding a mixt. of K, Ni, Co, Fe, and Bi nitrates simultaneously at const. pH 1-7 (pH preferably 3-5) and 20-80° (preferably 40-80°), holding the resulting suspension for 1-3 hr, adding silica gel, and heat treating at 180-200° for 10-50 hr.
