Method for producing conjugated fatty acid esters

摘要

Processes for preparing conjugated fatty acid products are described wherein (a) a composition which comprises a fatty acid ester having at least two unconjugated, carbon-carbon double bonds is provided; (b) the fatty acid ester is conjugated in the presence of a water-free base; (c) phosphoric acid is added to the conjugated fatty acid ester such that phosphate salts are precipitated; and (d) the precipitated phosphate salts are removed.
