Abstract
Process for obtaining pure 4,4-dioxydiphenylalkanes, characterized in that the 4,4'-dioxydiphenylalkanes are hot dissolved in aqueous phenol, the solution is cooled, the adducts that separate in crystalline form, are separated from the 4.4 dioxydiphenylalkanes and phenol, and from these by removal of the phenol by extraction or distillation, the 4,4'-dioxydiphenylalkanes are isolated.
