Systems and processes for thermolysis of polylactones to produce organic acids
First Claim
1. A process for producing an organic acid product, wherein the process comprises:
- a. introducing epoxide reagent and carbon monoxide reagent to a reaction vessel through a feed stream inlet, the reaction vessel comprising a separation chamber positioned above and in direct communication with a thermolysis chamber;
b. contacting the epoxide reagent and the carbon monoxide reagent with a carbonylation catalyst to produce a beta-lactone intermediate;
c. polymerizing the beta-lactone intermediate with a polymerization initiator in the presence of a metal cation to produce a polylactone product; and
d. heating the polylactone product under thermolysis conditions to produce the organic acid product.

Abstract
Reactor systems and processes produce organic acids through thermolysis of polylactones. The reactor systems and processes introduce at least one epoxide reagent and carbon monoxide reagent to at least one reaction vessel through at least one feed stream inlet. The epoxide reagent and carbon monoxide reagent contact at least one carbonylation catalyst to produce at least one beta-lactone intermediate. The beta-lactone intermediate is polymerized with at least one initiator in the presence of a metal cation to produce at least one polylactone product. The polylactone product is heated under thermolysis conditions to produce at least one organic acid product. The processes control the presence of contaminates, impurities, catalytic materials, and/or reagents to provide for highly pure organic acid products.
