Abstract
Crystalline and amorphous vanadyl polyphosphates (VO(PO3)(2)) with a P /V ratio = 2 were used as catalysts in the ammoxidation of toluene. Th e crystalline specimens exhibit a rather low activity compared with th e amorphous solid. The benzonitrile selectivities always reached nearl y 90%. Noticeable benzaldehyde amounts were detected that could be due to an inadequate ammonia activation on the solid surface.
