Abstract:
Provided are integrated processes for the conversion of beta propiolactone to acrylic acid. Systems for the production of acrylic acid are also provided.

Claim (Index 18):
A system for converting beta propiolactone to acrylic acid, comprising:\n (a) a reaction zone comprising beta propiolactone, a solvent, and a polymerization catalyst, wherein the reaction zone is a reactive distillation column configured to (i) operate at or above the pyrolysis temperature of poly(propiolactone), (ii) concurrently polymerize the beta propiolactone to poly(propiolactone) in the presence of the polymerization catalyst and thermally decompose the poly(propiolactone) to acrylic acid, and (iii) output a distillation stream comprising the solvent; and (b) a return loop configured to return a portion of the acrylic acid to the reaction zone.
