Acrylonitrile is produced from propylene in an excellent percent conversion of propylene, percent selectivity to acrylonitrile and percent yield of acrylonitrile, by bringing, at an elevated temperature, a reaction feed containing propylene, molecular oxygen and ammonia, each in gas phase, into contact with a catalyst consisting essentially of an oxide composition of the empirical formula:

Process for the catalytical preparation of acrylonitrile

Acrolein or methacrolein is produced in a high percent of yield by a catalytic oxidation of propylene or isobutylene in the presence of a catalyst of the empirical formula:
