Method for producing fatty acid monoesterified product using solid acid catalyst

Abstract

The present invention provides a method for producing a fatty acid monoester product by reacting an animal oil and/or a vegetable oil with an alcohol in the presence of a sulfonic acid group-introduced amorphous carbon catalyst and water. By this method, the production of a fatty acid monoglyceride, which is difficult to separate from the fatty acid monoester, can be suppressed, and the fatty acid monoester can be efficiently produced. Also, the present invention provides a method for producing a fatty acid monoester product by performing the transesterification reaction of an animal oil and/or a vegetable oil with an alcohol, or the esterification reaction of a fatty acid with an alcohol, in the presence of a sulfonic acid group-introduced amorphous carbon catalyst washed with water. By this method, the life of the catalyst can be extended, and the production cost can be reduced.
