Abstract
An isopropyl ester of an aliphatic acid containing from 2 to 8 carbon atoms is produced by a continuous process comprising maintaining at a temperature of from 60 DEG to 80 DEG C. a reaction mixture having the following composition :-strong mineral acid 15-30 per cent by weight, aliphatic acid 5-30 per cent by weight, the isopropyl ester of the aliphatic acid 5-10 per cent by weight, water 0.5-11 per cent by weight, the remainder being an isopropyl ester of the mineral acid, feeding the reaction mixture with the aliphatic acid at a rate sufficient to maintain the proportion thereof within the range stated above, continuously passing a gas containing at least 30 per cent by volume of propylene through the reaction mixture at a rate of from 2 to 5 cubic metres of gas per hour per kilogram of the reaction mixture, thereby providing an excess of propylene-containing gas sufficient to remove from the reaction mixture the isopropyl ester of the aliphatic acid as rapidly as it is produced. The preferred mineral acid is sulphuric acid. In the examples the isopropyl esters of (a) acetic acid, (b) butyric acid, and (c) octanoic acid are prepared by the process of the invention. U.S.A. Specification 2,079,652 is referred to.
