Date Jul. 10, 1993Light-colored lower alkyl oligoglucosides having a low polyglucose content can be obtained in short reaction times by a process in which a) aqueous glucose sirup is added to a mixture of a lower alcohol and an acidic catalyst at elevated temperatures via an inline mixer, b) the water present in the reaction mixture and the water released are azeotropically distilled off continuously and c) after the addition of glucose sirup, the reaction mixture is subjected to heating until at least 99% of the glucose is reacted.
