473. DEPPE SÖHNE, A., AND ZEITSCHEL, F. Separation of Alcohols and Phenols From Mixtures. British Patent 252,570, July 21, 1925. Chem. Abs., vol. 21. 1927, p. 2274.

Patent Abstracts

Alcohols and phenols are separated from mixtures in which the occur by treating the mixtures with H₃BO₃, arsenious acid, antimonious acid or phosphorous acid, or an anhydride of these acids or with a double anhydride of 1 of these acids and an organic acid such as HOAc, propionic, butyric, valeric, benzoic, or phthalic acid. An ester is obtained by the treatment, which on further treatment with a diluted alkali yields the alcohol or phenol. The process may be applied to obtain menthol from peppermint oil, geraniol from citronella oil, linalool from Shiu oil, benzyl alcohol from a mixture with benzyl acetate, terpineol and borneol from a camphor-oil fraction, and to various similar separations.
