Abstract
540. Bloxam, A. G., [Fabriques de produits de Chimie Organique de Laire]. Jan. 8. Alcohols. - A pleasant-smelling sesquiterpene alcohol, C15H26O, is extracted from such essential oils as those of cassia flowers and of ambrette or musk-seeds. To obtain this alcohol, essential oils containing it, or, better, the 150‹ to 200‹ C. fractions obtained when they are distilled at 20 mm. pressure, are treated with an acid anhydride such as phthalic, camphoric, or benzoic. The ether-like substances obtained are purified according to any well-known process, and are then saponified to liberate the alcohol. Those oils which contain saponifiable esters of the sesquiterpene alcohol are preferably treated with an alkali or alkaline earth first ; this treatment resinifies impurities as well as sets free the alcohol. The treatment with the acid anhydride may be repeated several times, and should be effected in the presence of a suitable solvent if the essence be rich in the alcohol, the solvent being omitted and the temperature raised if the essence be poor. An example of the treatment of oil of ambrette-seeds is given in the Specification. The pure product, obtained by repeated fractional distillation in vacuo, is an almost colourless oil, the uncorrected boiling point at 10 mm. pressure being 160‹ C. Specific gravity, 0À885 at 80‹ C. ; refractive index, nd = 1À488.
