A process and novel catalyst for the production of acrylonitrile, acetonitrile and hydrogen cyanide characterized by the relative yields of acrylonitrile, acetonitrile and hydrogen cyanide produced in the process and by the catalyst, which are defined by the following: α=[(% AN+(3×% HCN)+(1.5×% ACN))÷% PC]×100 wherein % AN is the Acrylonitrile Yield and % AN≧81, % HCN is the Hydrogen Cyanide Yield, % ACN is the Acetonitrile Yield, % PC is the Propylene Conversion, and α is greater than 100.
