Abstract
Alkali metal ions are separated off from alkoxylates containing alkali metal ions by a process comprising:a) dilution of the alkali metal-containing alkoxylate with an inert solvent,b) treatment of the alkali metal-containing solution of the alkoxylate with a cationic exchanger in order to obtain a substantially alkali metal-free solution of the alkoxylate, andc) removal of the solvent from the substantially alkali metal-free solution of the alkoxylate in order to obtain a substantially alkali metal-free and substantially solvent-free alkoxylate.
