Abstract
The dark-colored solutions obtained in the preparation of butyloligoglycosides from saccharides and butanol are adjusted to an acidity of 0 to 12 mg of KOH/g. Colorless or light-colored butyloligoglycosides are then extracted from them by water, optionally after the addition of a nonpolar solvent, and are then isolated from the aqueous phase in a conventional way.
