摘要

An improved method for synthesizing alkylpolyglucosides comprising reacting a glycoside with a long-chain alcohol in the presence of a novel type of catalyst, constituted by an alkali or aryl sulfonic acid, wherein the sulfonic group is sterically hindered. Using these catalysts, a raw product is obtained which is practically free from byproducts. The resulting alkyl polyglucosides are completely biodegradable surfactants and can be used to formulate detergents.
