Abstract

Vanadia supported on a silica-alumina or gamma-alumina support in an amount to provide a vanadia to support weight ratio ranging from about 0.3:1 to about 3:1 substantially entirely within the pores of the support, the vanadia having been placed in molten form substantially within the pores of a support having a surface area greater than about 50m.sup.2 gram, a porosity greater than about 0.4 cc/gram which further includes an alkali metal, with the vanadium metal to alkali metal mole ratio being from 2:1 to 30:1. At least a portion of the alkali metal is preferably in the form of alkali metal vanadate. The catalyst is used for the production of nitriles from a compound containing at least one alkyl group.
