ABSTRACT:
Aliphatic alcohols with up to 30 and especially with 6 to 18 carbon atoms are separated from a mixture of alkyl glycosides and alcohols which are unreacted during the production of these glycosides, by single or multi-stage distillation. The alcohols are distilled off by a drop film evaporator to impoverish the reaction mixture to residual alcohol contents of 5 wt % and under. The strip load of the drop film evaporator is set to at least 1.0 m.sup.3 /h m, especially at least 1.8 m.sup.3 /h m and preferably at least 3.0 m.sup.3 /h m. It is possible to reduce the alcohol content of the product to any value between 0.1 and 5 wt % at acceptable overall cost.
