Provided are: novel zeolite having an extremely small amount of specific Bronsted acid sites on the surface thereof, which is expected to be useful as a catalyst for the aromatization of a non-aromatic hydrocarbon typified by an aliphatic hydrocarbon; and a catalyst for use in the production of an aromatic hydrocarbon, which comprises the zeolite. Zeolite characterized by satisfying the following requirements (i) to (iii). (i) The zeolite has an average particle diameter of 100 nm or less. (ii) The zeolite is 10-membered ring microporous zeolite. (iii) The amount of the Bronsted acid sites on the outer surface of the zeolite is 0.1 to 10.0 μmol/g.

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.

Process for producing benzyl acetate and benzyl alcohol

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.
