Abstract

Provided herein are reactor systems and processes for producing organic acids directly from beta-lactones. Such reactor systems and processes involve the use of a heterogeneous catalyst, such as a zeolite at vapor phase conditions. The reactor systems and processes may use a fixed bed, moving bed or fluidized contacting zone as reactor configurations.

No. 15 / 464,346, filed Mar. 21, 2017, which claims benefit from U.S. Provisional Application No. 62 / 311,262, filed Mar. 21, 2016, which are hereby incorporated by reference in their entireties as if fully restated herein.FIELD OF THE INVENTION

[0002] This invention generally relates to reactor systems and processes for producing organic acids directly form beta-lactones.BACKGROUND OF THE INVENTION

[0003] The production and use of organic acids such as acrylic acid (AA) has grown significantly in recent decades as the demand for polyorganic acids such as polyacrylic acid-based superabsorbent polymers (SAPs) has grown. SAPs are used extensively for the manufacture of diapers, adult incontinence products, and feminine hygiene products, as well as in agricultural applications.

[0004] Currently, commercial acrylic acid is typ...
