Abstract
The preparation of alkyl oligoglycosides by transglycosidation of C.sub.2 to C.sub.6 alkyl glycosides using C.sub.8 to C.sub.20 fatty alcohols is improved by the fact that the fatty alcohol is preheated to at least 80.degree. C., it is mixed with the alkyl glycoside, then the reaction is performed and C.sub.2 to C.sub.6 alcohol is flashed off under vacuum after the reaction. Products having a good color are obtained. Encrustation and cracking in the equipment do not occur.
