Abstract
Oxo alcohols are separated from higher boiling impurities by liquid-liquid extraction with an aqueous solution of at least 25, preferably 35-40 per cent by weight, of a water-soluble salt of an organic sulphonic acid, preferably an alkali metal salt of an aromatic sulphonic acid, such as sulphonates of benzene or alkyl benzenes, the alkyl groups having 1-5 carbon atoms. Aliphatic sulphonates are also suitable. Sodium benzene, toluene, p-cymene, mixed xylene and n-butyl sulphonates are most suitable. Potassium, lithium, ammonium or amine salts, and salts of naphthalene, dimethylaniline, naphthol, naphthylamine, nitrobenzene, cyclohexane, lauryl, methane, ethane, and anthraquinone sulphonic acids are also specified. The bottoms after distilling off Oxo alcohols is treated with the sulphonate solution, the aqueous phase separated, and the alcohol recovered, preferably by steam stripping. Alcohols of C4-C15 may be treated. Increasing the ratio of solvent to alcohol gives increased recovery. In examples, crude iso-octyl alcohol or bottoms after distillation is extracted with solutions of sodium xylene sulphonates or sodium n-butyl sulphonate in ratios from 1 : 1 to 25 : 1, and of concentrations between 35 and 46 per cent, in one or more stages. Specifications 686,904 and 24138/48 (as open to inspection under Sect. 91) are referred to.
