1. A process for producing an acrylonitrile product, comprising:

  • introducing an epoxide reagent and a carbon monoxide reagent to at least one reaction vessel through at least one feed stream inlet;

    contacting the epoxide reagent and the carbon monoxide reagent with a carbonylation catalyst in the at least one reaction vessel to produce a beta-lactone intermediate;

    converting the beta-lactone intermediate to an organic acid intermediate; and

    reacting the organic acid intermediate with an ammonia reagent under ammoxidation conditions in the at least one reaction vessel to produce the acrylonitrile product.
