Abstract
Perfluorosulfonic acid resin membranes are active catalysts for the hydration and polymerization of isobutene and dehydration of t-butanol. The membranes offer unique advantages for hydration and dehydration since they are semi-permeable to water and impermeable to hydrocarbons.
Claims9
A process for producing t-butanol comprising contacting isobutene and water with a membrane of a perfluorosulfonic acid resin which is the copolymer of sulfonyl fluorovinyl ether and a fluorocarbon at a temperature in the range of about 0.degree. to 150.degree. C, said membrane separating said isobutene and water and recovering a product containing t-butanol.
In the process for the preparation of the t-butanol by reacting isobutene and water in the presence of an acid catalyst at temperatures in the range of about 120.degree. to 150.degree. C, wherein the improvement comprises employing as the acid catalyst a membrane of a perfluorosulfonic acid resin which is the copolymer of sulfonyl fluorovinyl ether and a fluorocarbon, contacting isobutene with one side of said membrane and water with the other side thereof, said membrane separating said isobutene and water and recovering t-butanol from said isobutene contacting said membrane.
The process according to claim 17 wherein said membrane is about 2 to 20 mils thick.
