Title:
MANUFACTURE OF POLYOL FATTY ACID POLYESTER
Document Type and Number:
Japanese Patent JPS6366151
Kind Code:
A
Abstract:
A process for preparing polyol fatty acid polyesters, e.g. sucrose polyesters (SPE) is improved by (1) mixing the polyol with an alkaline catalyst such as KOH, NaOH or their carbonates, preferably in aqueous solution or dissolved in C1-5 alcohols or ketones at atmospheric pressure and 10-80 DEG C, (2) preparing a mixture of fatty acid lower alkyl esters with an emulsifier, preferably a fatty acid soap, and (3) adding the alkaline polyol solution to the mixture of (2), whereby preferably the solvent is removed during the addition of (1) to (2), e.g. at 60 DEG C and 5 mbar. The ratio fatty acid lower alkyl esters : polyol is preferably (10-20):1. The reaction is improved so that SPE are formed at 110-145 DEG C within 5-10 hours.
