Abstract

In the production of alcohols by treating olefines such as those from the cracking of mineral oils, with sulphuric acid, polymers are removed from the absorption product (which may be first hydrolyzed) by extraction with solvents of low boiling-point such as benzene, toluene, xylene, carbon tetrachloride, ethylene chloride, trichlorethylene, benzine fractions having high aromatic content such as benzine fractions derived from Borneo oils, also cyclohexane and isopropyl acetate. The solvents are also used as entraining agents in the azeotropic distillation of the dilute alcoholic distillate. The extraction treatment is preferably applied to the hydrolyzed alkyl sulphuric acid, and, where losses of alcohol are liable to occur, the extraction may be effected in the manner described in Specification 355,294, [Group III], water or dilute sulphuric acid being used as second washing liquid. In an example, propylene is absorbed in 96 per cent sulphuric acid at 0--10 DEG C. and the product is diluted and hydrolyzed, the hydrolyzed product being washed with water and benzene. The purified solution is then distilled yielding an alcohol of 79,2 per cent and residual sulphuric acid of about 30 per cent.
