ABSTRACT:
The present invention relates to a process for preparing an alkyl ester of a fatty acid wherein a transesterification reaction is carried out between a fat or oil and an alcohol in the presence of a catalyst comprising a composite metal oxide having a perovskite structure; and a process for preparing an alkyl ester of a fatty acid wherein a transesterification reaction is carried out between a fat or oil and an alcohol in the presence of a catalyst comprising at least one member selected from the group consisting of oxides, hydroxides and carbonates of alkaline earth metals is used as the catalyst, with the alcohol made into a supercritical state or subcritical state. According to the present invention, the alkyl ester of a fatty acid which can be effectively utilized as a diesel fuel oil or the like can be prepared at high efficiency and on an industrial scale mainly from triglyceride contained in a fat or oil, especially a waste oil.
