HYDROGENATED FATTY ACID ALKYL ESTER FOR PRODUCING FATTY ACID ALKYL ESTER SULFONATE AND METHOD FOR PRODUCING THE SAME, FATTY ACID ALKYL ESTER SULFONATE AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a hydrogenated fatty acid alkyl ester enabling a fatty acid alkyl ester sulfonate having excellent color to be produced stably, and useful for the production of the fatty acid alkyl ester sulfonate, to provide the hydrogenated fatty acid alkyl ester, to provide a method for producing the fatty acid alkyl ester sulfonate, and to provide the fatty acid alkyl ester sulfonate.;SOLUTION: The method for producing the hydrogenated fatty acid alkyl ester usable for the method for producing the fatty acid alkyl ester sulfonate including a sulfonation step of sulfonating the hydrogenated fatty acid alkyl ester in the presence of a discoloring inhibitor, and subsequently carrying out aging, a neutralization step of neutralizing the obtained sulfonated compound, and a step of bleaching the obtained neutralized product includes a hydrogenation step of hydrogenating the non-hydrogenated fatty acid alkyl ester so as to have 0.2 iodine number, wherein the non-hydrogenated fatty acid alkyl ester having 5 meq./kg peroxide value is selected and used for the hydrogenation step.;COPYRIGHT: (C)2009,JPO&INPIT
