Abstract

334,228. Woolcock, J. W., and Imperial Chemical Industries, Ltd. April 30, 1929. Isopropyl sulphates and acetates; isopropanol; ethanol.- Propylene is absorbed in mixtures of acetic acid with sulphuric acid or with acid isopropyl sulphate in suitable proportions, if desired in the presence, of solvents such as isopropyl alcohol, at temperatures not exceeding 60‹ C. Isopropyl sulphates and isopropyl acetate are formed. The isopropyl acetate may be recovered by distillation or may be separated as a top layer on the addition of water to the mixture, and the sulphuric esters are converted into isopropyl alcohol by hydrolysis. Before separating the isopropyl acetate, any desired proportion thereof may be converted into isopropyl alcohol by a controlled heating of the mixture after the addition of water. Propylene may be separated from mixtures thereof with other gases including olefines by first absorbing the higher olefines in cooled 80 per cent sulphuric acid, then absorbing the propylene as described above, ethylene being substantially unabsorbed. Ethylene separated from propylene in this way may subsequently be absorbed in concentrated sulphuric acid for the production of ethyl alcohol. Examples are given. Specification 173,786 is referred to.
