The title catalyst was made by impregnating silica gel (which was obtained by pptg. from a water glass soln. with salts of a strong acid and a weak base) with V-contg. materials followed by evapg., molding, drying, and calcining. In order to increase the activity of the catalyst, silica gel with 100-30,000 Å pore was used and it was activated with H2SO4 or ammonium sulfate.
