Abstract
Provided herein are methods of producing acrylic acid from beta-propiolactone. Such methods may involve the use of a heterogeneous catalyst, such as a zeolite.
Claims17
A method of producing acrylic acid from beta-propiolactone, comprising:
- combining beta-propiolactone, a zeolite, and a polymerization inhibitor;
- producing acrylic acid from at least a portion of the beta-propiolactone;
- wherein the beta-propiolactone, the polymerization inhibitor, and the zeolite are combined neat or with a polar aprotic solvent;
- and wherein the produced acrylic acid has a purity of at least 95% and a yield of at least 90%.
