Disclosed is a catalyst composition which does not contain antimony or molybdenum for the vapor phase ammoxidation of alkanes of the general empirical formula:VWBiMOwherein M is one or more elements selected from sodium, cesium, magnesium, calcium, barium, boron, yttrium, indium, aluminum, gallium, tin, titanium, silicon, zirconium, germanium, niobium and tantalum, a is 0.2 to 10, b is 0.5 to 5, c is 0 to 10 and x is determined by the valence requirements of the elements present. The catalyst precursor is precipitated from a solution or slurry of compounds of vanadium, tungsten, bismuth and, optionally, M, then separated, dried and calcined to give a phase or combination of phases active in the ammoxidation of low-weight paraffins to the corresponding unsaturated mononitriles. Nitriles may be produced in a gas phase catalytic reaction of alkanes with ammonia and oxygen in the presence of the catalyst.

A process for the vapor phase ammoxidation of alkanes and olefins with a catalyst of the general empirical formula:VSbMQOwherein M is at least one element selected from magnesium, aluminum, zirconium, silicon, hafnium, titanium and niobium, Q is at least one element selected from rhenium, tungsten, molybdenum, tantalum, manganese, phosphorus, cerium, tin, boron, scandium, bismuth, gallium, indium, iron, chromium, lanthanum, yttrium, zinc, cobalt, nickel, cadmium, copper, strontium, barium, calcium, silver, potassium, sodium and cesium, a is 0.5 to 20, b is 2 to 50, c is 0 to 10 and x is determined by the valence requirements of the elements present. The process has a co-feed of gaseous carbon dioxide with an alkane (paraffin) and/or alkene, ammonia and an oxygen-containing gas which react in the presence of the catalyst to form a nitrile and by-products.
