Abstract:
The subject matter of the invention is a method for the removal of alkaline or acidic compounds from a solvent-containing metal oxide dispersion, having the following steps: a. conversion of the solvent into gas phase; b. condensation of the solvent; c. bringing the condensed solvent into contact with a neutralizing agent; d. Return of the condensed solvent into the metal oxide dispersion.
