摘要：

The catalytic properties of vanadium-titanium oxide system in ammoxidation of methylpyrazine have been studied. Catalytic activity increases monotonically and yield of selective products passes a wide maximum in the range of V2O5 content from 10 to 75 wt.% with increase in the V/Ti relation. The active centers of binary catalysts include V5+ cations with distorted octahedral coordination strongly bounded with titania apparently owing to formation of V-O-Ti bonds.
