Inventor: MATSUMOTO SHUSAKU
IPC: C07H1/06
Filed: 1989-06-07
Abstract: PURPOSE:To purify the subject hydrous compound on an industrial scale without using an organic solvent by adjusting the pH of a reaction mixture for the synthesis of a sucrose fatty acid ester in aqueous medium to a neutral region, adding a neutral salt to the system and subjecting the formed precipitate to a specific treatment. CONSTITUTION:A sucrose fatty acid ester (SE) is synthesized in an aqueous medium to obtain a reaction mixture containing the objective SE, unreacted sugar, unreacted fatty acid methyl ester, a catalyst, a soap and a fatty acid. The pH of a reaction mixture is adjusted to a neutral region, preferably at pH7.5 and the mixture is mixed with water and a neutral salt to precipitate the SE. The precipitate is washed with an acidic water (preferably water of normal temperature having pH of 3-5.5) and a fatty acid is added to the cleaned liquid to precipitate the SE having high HLB value. Finally, the precipitate is neutralized to obtain the objective compound. Preferably, the reaction mixture is heated at 50-80 deg.C after the pH-adjustment.
