Acrylonitrile derivatives from epoxide and carbon monoxide reagents
First Claim
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.

Abstract
The present invention is directed to reactor systems and processes for producing acrylonitrile and acrylonitrile derivatives. In preferred embodiments of the present invention, the processes comprise the following steps: introducing an epoxide reagent and carbon monoxide reagent to at least one reaction vessel through at least one feed stream inlet; contacting the epoxide reagent and carbon monoxide reagent with a carbonylation catalyst to produce a beta-lactone intermediate; polymerizing the beta-lactone intermediate with an initiator in the presence of a metal cation to produce a polylactone product; heating the polylactone product under thermolysis conditions to produce an organic acid product; optionally esterifying the organic acid product to produce one or more ester products; and reacting the organic acid product and/or ester product with an ammonia reagent under ammoxidation conditions to produce an acrylonitrile product.
