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 20):
A system for producing acrylic acid, comprising:\n a beta propiolactone source; a polymerization catalyst source; and a reactor comprising:\n at least one inlet to receive beta propiolactone in a solvent from the beta propiolactone source and a polymerization catalyst from the polymerization catalyst source, \n at least one outlet to output an acrylic acid stream and a distillation stream comprising the solvent, \n wherein the reactor is configured to (i) polymerize the beta propiolactone to produce poly(propiolactone) in the presence of the polymerization catalyst at or above the pyrolysis temperature of poly(propiolactone), (ii) concurrently thermally decompose the poly(propiolactone) to produce acrylic acid in situ, (iii) output the acrylic acid stream, and (iv) output the distillation stream.
