Abstract: Methods for the removal of ionic contaminants from a hydrophilic organic solvent by a mixed bed of ion exchange resins are described. A mixed bed of ion exchange resins with gel-type strong-acid cationic ion exchange resin with a specific moisture holding capacity and gel-type anionic ion exchange resin is used in some embodiments of such methods.
