Methods for the synthesis of acrylic acid and derivatives from fumaric acid

摘要

The present invention relates to a process for producing an olefin. Said process comprises the steps of:
(a) culturing by fermentation in a sufficient amount of nutrients and media a microbial organism that produces a first olefin, and
(b) contacting said first olefin with a sufficient amount of a disubstituted alkene in the presence of an olefin metathesis transformation catalyst to produce second, different olefin.
Preferably, the first olefin is fumaric acid or a fumarate diester and the second olefin is acrylic acid or an acrylate ester.
