Abstract
Methods are provided for refining natural oil feedstocks and producing dibasic esters and/or dibasic acids. The methods comprise reacting a terminal olefin with an internal olefin in the presence of a metathesis catalyst to form a dibasic ester and/or dibasic acid. In certain embodiments, the olefin esters are formed by reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters, separating the olefins from the esters in the metathesized product, and transesterifying the esters in the presence of an alcohol to form a transesterified product having olefin esters.
Claims20
A method of refining a natural oil, comprising:
- providing a terminal olefin ester and an internal olefin ester, wherein the terminal olefin ester is an ester of 9-decenoic acid and the internal olefin ester is an ester of 9-dodecenoic acid;
- and
- reacting the terminal olefin ester with the internal olefin ester in the presence of a metathesis catalyst to form a dibasic ester of 9-octadecenedioic acid and 1-butene.
