Title:
METHOD FOR PRODUCING FATTY ACID ESTER
Document Type and Number:
WIPO Patent Application WO/2010/061702
Kind Code:
A1
Abstract:
A method for producing a fatty acid ester, wherein a fatty acid can be efficiently produced at low cost by having a transesterification reaction proceed at a high reaction rate under mild conditions without requiring a catalyst separation process. In the method, wherein a fatty acid ester is produced by a transesterification reaction between an alcohol and a fat or oil, a hydrogen sulfate of an organic onium compound is used as a catalyst. Since the hydrogen sulfate can produce a fatty acid ester more efficiently using sulfuric acid as a starting material, the production cost can be reduced when compared with the conventional triflate salts.
