Process for the preparation of polyalkyleneetherglycols containing heteropoly acids |
| abstract |
Process for the purification of crude polyalkylene ether glycols which are contaminated by heteropolyacids or their salts by treatment with solvent, characterized in that the crude polyalkylene ether glycols are mixed with a liquid hydrocarbon and water and the purified polyalkylene ether glycols are isolated from the upper phase after phase separation. |
