Abstract
Provided is a process for producing a fatty acid alkylester through a transesterification of triglyceride contained in a fat and oil by causing the fat and oil and an alcohol to react with each other. In this process, the reaction is performed in an atmosphere in which the alcohol is in super-critical state in the absence of a metal alkali catalyst and an acid catalyst. This makes it possible to eliminate a pre-treatment process for esterifying free fatty acids contained in the fat and oil and, in addition, to eliminate or simplify recovering and refining processes of the reaction product by suppressing the by-production of a fatty acid soap.
