Abstract
An improved process for preparing an alkylpolyglycoside wherein the alkyl group contains about 8 to about 20 carbon atoms, prepared by reacting a saccharide and an alcohol in the presence of an acid catalyst, and subsequently removing excess unreacted alcohol, the improvement comprising adding to the reaction product an oxide, such as MgO, and removing the excess unreacted alcohol by thin film evaporation under vacuum at temperatures up to about 240.degree. C. under sparging or non-sparging condition with an inert gas.
