Methods for preparing acrylic acid from biobased starting materials |
| abstract |
Described herein are methods for preparing acrylic acid from biobased starting materials, e.g., ethanol. One aspect of the present invention provides a method for preparing acrylic acid comprising the followings steps: (a) providing a source of ethanol; (b) carbonylating the ethanol in the presence of a metal catalyst to obtain propanoic acid; (c) halogenating the propanoic acid to obtain halopropanoic acid; (d) heating the halopropanoic acid in the presence of an inorganic base; and (e) recovering acrylic acid. |
