    Abstract: PURPOSE:To obtain the fatty acid ester giving soaps extremely good in their smells by ester-exchanging palm oil, etc., with a lower alcohol, hydrogenating the product, and subsequently distilling to obtain the fraction. CONSTITUTION:For example, palm oil, palm nuclear oil or their mixture is ester-exchanged with a lover alcohol to produce a palm oil fatty acid lower alcohol ester, a palm oil nuclear fatty acid lower alcohol ester or their mixture. The ester or ester mixture is hydrogenated in the presence of a hydrogenation catalyst to reduce the linolic acid ester content of the ester in an amount of 10wt.% or more based on the linolic acid content of the non-hydrogenated ester, followed by distilling the hydrogenation product to provide a fraction for the objective ester.

    Abstract: PURPOSE:To improve the rate of reaction and to make an apparatus for preparing soap compact in size by adding a monoglyceride and/or a diglyceride to a reaction mixture in the saponification step in the production of soap by ester saponification. CONSTITUTION:A monoglyceride and/or a diglyceride is added to a reaction mixture in the saponification step in the production of soap by saponification of fatty acid/lower alcohol esters. It is preferable to add 1-20wt.% monoglyceride and/or diglyceride to the esters. The esters used are those of a 1-5C alcohol with a fatty acid having an 8-24C alkyl or alkenyl group. Any glycerides derived from long-chain fatty acids may be used for the above glycerides. However, those monoglycerides and diglycerides which have fatty acid compositions corresponding to the fatty acid/lower alcohol esters as the raw material of soap are preferable in terms of physical properties of the soap to be obtained.
