Abstract

1443106 t-Butanol MITSUBISHI RAYON CO Ltd 11 June 1974 [25 July 1973 7 March 1974] 25883/74 Heading C2C t-Butanol is obtained by reacting isobutene with water at 20-120‹ C. in the presence of a strong acid ion-exchange resin and an organic acid under conditions such that the liquid product obtained is a homogeneous solution. In a preferred embodiment, (1) isobutene or a hydrocarbon mixture containing it reacts with an aqueous organic acid solution in the presence of the resin, (2) unaltered hydrocarbons are removed by distillation, (3) the residual mixture is distilled to give a mixture (A) consisting mainly of t-butanol and organic acid ester thereof, and an aqueous organic acid solution (B), (4) A, with if necessary further water, is treated with acid resin to hydrolyse the ester, (5) the hydrolysed product is separated into an aqueous t-butanol solution (C) and an aqueous organic acid solution (D), and (6) D is recycled to step 1. In an example, step 1 is carried out in two reactors, the first of a complete mixing type and the second of plug flow type. The organic acid is preferably a C 1 -C 6 saturated aliphatic acid (e.g. acetic or propionic acid). Isobutene may be reacted selectively in the presence of other hydrocarbons, e.g. n-butenes and butanes.
