摘要: Benzyl alcohol of high purity is produced by supplying benzyl acetate, water and acetic acid to a hydrolysis reactor packed with a solid acid catalyst. The liquid reaction mixture produced, which contains benzyl acetate, water, benzyl alcohol and acetic acid, is supplied to an acetic acid-water recovery column, Benzyl alcohol and benzyl acetate are recovered while acetic acid is removed and returned to the hydrolysis reactor.

摘要: The present invention relates to a process for producing benzyl acetate and benzyl alcohol.Benzyl acetate itself is useful as a solvent and a perfume. Benzyl alcohol which is derived from the benzyl acetate by hydrolysis or by transesterification with methanol is an important compound useful as a powerful solvent, a nontoxic medical additive, and an intermediate compound for agricultural chemicals and medicines.

摘要: 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.
