<p>A method of producing a fatty acid alkyl ester for diesel fuel oil starting with a fat material such as an edible oil whereby the qualities required as diesel fuel oil can be satisfied and the wastes from the production process can be minimized. This method is characterized by comprising subjecting a fat material to an ester exchange reaction with an alcohol, washing with water the oily phase of the reaction mixture, eliminating the water after washing via absorption by a high water-absorptive resin, and then separating the high water-absorptive resin gel to thereby give a fatty acid alkyl ester appropriate for diesel fuel oil.</p> |
