Abstract: A process for producing a polymer having sulfonic acid groups is provided which comprises treating a polymer having sulfonate salt groups with a ion-exchange resin to change the sulfonate salt groups into sulfonate acid groups with porous-type strongly acidic cation exchange resin. A process for producing a tertiary alcohol is also provided which comprises hydration of olefin by use of the aforementioned polymer as the catalyst. By the process, a tertiary alcohol is produced by hydration of olefin with high selectivity at low cost.

Abstract: PURPOSE:To obtain a method for economically producing tert-butanol in high activity and yield according to the hydrating reaction of isobutene and a method for producing a catalyst used therefor. CONSTITUTION:A polystyrenesulfonate is subjected to ion exchange using a porous type strong acidic cation exchange resin to provide polystyrenesulfonic acid, which is then used as a catalyst to produce tert-butanol from isobutene. The resultant reactional solution is then separated into two phases of a layer containing the catalyst and a layer without containing the catalyst. Thereby, the tert-butanol is recovered.

Abstract: PURPOSE:To produce an unsaturated carboxylic acid ester in a high-space-time yield by a new catalytic preparation method. CONSTITUTION:An olefin is made to react with oxygen and acetic acid in a vapor phase in the presence of a palladium catalyst prepared by subjecting a palladium ammonium complex to ion exchange with the surface hydroxyl group of a catalyst support, then subjecting the ion-exchanged complex to reduction treatment and further carrying an alkali metal acetic acid salt on a catalyst support to produce the objective unsaturated carboxylic acid ester.
