Abstract

Alkyl polyglucosides were synthesized by solvent-free glycosidation using ultrasonic emulsification. We examined glycosidation conditions of fatty alcohol with glucose hydrate and anhydrous glucose in the presence of p-toluenesulfonic acid. Glucose was emulsified in a molar excess of fatty alcohol for 20 minutes with a ultra-sonicator at room temperature and converted in a stirred reactor to more than 95% polyglucoside within $2.5{\sim}3.5$ hr under $20{\sim}30$ mmHg at $110^{\circ}C$ with a three-fold molar ratio of fatty alcohol to glucose in the presence of 1mol% p-toluenesulfonic acid. It was possible to obtain a polyglucoside mixture of HLB 13 consisting of 65% monoglucoside and 35% oligoglucoside with less than 1% of fatty alcohol.
