Gives process for purification of synthesized alcohols by removal of carbonyl impurities. Adding a carbonylcondensing agent such as aldehydes or ketones in the presence of a basic condensation catalyst results in conversion of the carbonyl compounds into complexes of higher molecular weight and lower volatility. A highly purified product and valuable hydroxy byproducts are recovered. 3 literature refs., 3 foreign patents, and 5 United States patents cited.
