Process for the purification of alkylene oxide adducts |
| abstract |
A novel process for the purification of an alkylene oxide adduct which has been prepared using halogen-containing metal catalysts and contains halogen-containing compounds and also metals as impurities comprises treating the alkylene oxide adduct which is to be purified with an excess of alkali metal compound and adjusting the pH of the alkaline mixture obtained to a value of at most 7 using an acid, with the proviso that the water content of the product mixture which is then present is at least 0.1% by weight, relative to the weight of the product. This product mixture is freed from water and other solvents, this resulting in the precipitation in coarse crystalline form of salts which are insoluble in the alkylene oxide adduct and which can be easily separated off to isolate the desired pure alkylene oxide adduct. |
