Abstract

The alcohols or ethers produced by hydrolysis of the products obtained by absorption of olefines in strong acids such as sulphuric or phosphoric acid, are separated by adding an organic liquid acting to extract the alcohol or ether or to entrain the alcohol or ether and if desired the water in a distillation process. Suitable liquids are benzene, decahydronaphthalene, tetrachlorethane, chlorbenzene, and petroleum fractions of boiling-point between 80 and 150 DEG C. When the added liquid is to be used as a solvent, chlorbenzene, hydrogenated naphthalenes, or tetrachlorethane are suitable in the case of ethyl alcohol, while for entraining ethyl alcohol, benzene, trichlorethylene n-hexane, cyclohexane, and chloroform are suitable, while diethyl ether may be entrained by n-pentane. When an entraining agent is employed, it may be brought into contact with the alcoholic liquor in liquid or vapour form, and the solvent layer of the distillate may be returned to the distillation apparatus. A salt such as ammonium sulphate may be added to the alcoholic liquor before extraction of the alcohol. In examples (1) the product of the absorption of ethylene in sulphuric acid is diluted with ammonium sulphate solution and extracted with chlorbenzene in two stages; (2) the hydrolysis product of the absorption of isobutylene in sulphuric acid is extracted with benzene in three stages; an aqueous solution of the alcohol may be obtained by treating the extract with water; (3) the hydrolyzed product of the absorption of propylene in sulphuric acid is distilled with n-hexane; (4) the hydrolyzed product of the absorption of ethylene in sulphuric acid is distilled with cyclohexane or benzene; (5) the same hydrolysis product is passed down a column, the top of which is maintained at 70 DEG C. and n-hexane vapour is passed up the column. Specification 389,134 is referred to.
