METHOD FOR PRODUCTION OF FATTY ACID ALKYL ESTER USING OIL-AND-FAT AS RAW MATERIAL

摘要

Disclosed is a method for producing a fatty acid alkyl ester by utilizing the transesterification of an oil-and-fat with an aliphatic alcohol in the presence of a small quantity of a catalyst at a temperature around or lower than the boiling point of the aliphatic alcohol used for the production of the fatty acid alkyl ester, which can produce the fatty acid alkyl ester in high yield in spite of conducting the transesterification for a short period. Specifically disclosed is a method for producing a fatty acid alkyl ester, which comprises the step of reacting an oil-and-fat with an aliphatic alcohol represented by the formula: ROH [wherein R represents an alkyl group having 1 to 6 carbon atoms] in the presence of calcium oxide having a BET specific surface area of 20 m²/g or more and a total pore volume of pores each having a particle diameter of 2 to 100 nm of 0.15 mL/g or more.
