Abstract

A vanadium-titanium catalyst was used in the preparation of aromatic nitriles by ammoxidation in a fixed-bed reactor. The catalyst prepared by the mixing method showed high conversion (91 %) and selectivity (95 %) in the ammoxidation of 2-picoline. The effect of varied conditions on the ammoxidation of 2-picoline was also explored, including LHSV, H2O/NH3 molar ratio, reaction temperature, and the catalyst calcination temperature. This catalyst was also used in the ammoxidation of 3-picoline, 4-picoline, and toluene derivatives.
