Title:
PRODUCTION OF SUCROSE FATTY ACID ESTER
Document Type and Number:
Japanese Patent JPH07228590
Kind Code:
A
Abstract:

PURPOSE: To obtain a sucrose fatty acid ester industrially, advantageously and in high yield.

CONSTITUTION: In a production process in which sucrose and a fatty acid alkyl ester (SE) are reacted in DMSO solvent to obtain a sucrose fatty acid ester, a reaction mixture is allowed to liquid-liquid extraction in the condition of pH3-7 by using an organic solvent and water to obtain an organic solvent solution containing the SE. Then, the organic solvent solution is allowed to liquid- liquid extraction by using water in a continuous counter current extraction and DMSO remaining in the organic solvent solution is removed. The organic solvent solution thus obtained essentially containing no DMSO is concentrated to produce the sucrose fatty acid ester.
