Claims
- 1. A process for preparing a tertiary alcohol comprising hydrating an olefin in the presence of polystyrenesulfonic acid or polyvinylsulfonic acid as a catalyst in liquid form which is soluble in water or the olefin.
- 2. The process of claim 1 wherein the olefin is isobutene and the tertiary alcohol is tertiary butanol.
- 3. The process of claim 1 wherein the olefin is hydrated continuously in a counter-current reactor.
- 4. A homogeneous process for preparing a tertiary alcohol comprising the steps of:
- (1) hydrating an olefin selected for the group consisting of isobutene, .alpha.- methylstyrene, isoprene or mixtures thereof in an aqueous solution, optionally in the presence of an inert solvent, at a temperature of from 30.degree. to 120.degree. C. and at a pressure from atmospheric up to 30 kg/cm.sup.2 in the presence of polystyrene sulfonic acid or polyvinylsulfonic acid as a catalyst soluble in the aqueous solution, the olefin or both, and thereafter
- (2) separating the catalyst in liquid form and from the so produced tertiary alcohol.
- 5. The process of claim 4 wherein following hydration the reaction mixture is separated into one phase containing the liquid catalyst and another phase containing no catalyst.
- 6. The process of claim 4 wherein the reaction solution following hydration is separated by filtration into the tertiary alcohol and an aqueous catalyst solution.
- 7. The process of claim 4 wherein the aqueous solution also contains an inert solvent selected from the group consisting of butanes, pentanes, hexanes, cyclohexane, benzne, toluene, xylene and alcohols.
