Abstract:
1. A process comprising a) culturing by fermentation in a sufficient amount of nutrients and media a microbial organism that produces fumaric acid; b) esterification of said fumaric acid to provide a fumarate diester; and c) olefin metathesis of said fumarate diester to an acrylate ester in the presence of an olefin metathesis catalyst selected from ruthenium, [1,3-bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene]dichloro[[2-(1-methoxy)phenyl]methylene], [1,3-Bis(2-methylphenyl)-2-imidazolidene]dichloro(benzylidene) (tricyclohexylphosphine) ruthenium (II), ruthenium, dichloro(phenylmethylene)bis(tricyclohexylphospine), [1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene]dichloro(3-methyl-2-butenylidene)(tricyclohexylphosphine) ruthenium (II), and ruthenium, [1,3-bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene]dichloro(phenylmethylene)(tricyclohexylphosphine).
