    摘要: A process for purifying C.sub.8 -C.sub.16 -alkylglycosides which have been obtained by reacting lower alkylglycosides or hydroxyalkylglycosides with C.sub.8 -C.sub.16 -alcohols in the presence of an acid catalyst, by distillative removal of unconverted C.sub.8 -C.sub.16 -alcohols, wherein the distillative removal, at least of the last amounts of unconverted alcohols, is carried out in the presence of glycols whose boiling points are at most 10.degree. above, and at most 30.degree. below, those of the alcohols to be removed.
