(A) CYCLANIC, CYCLENIC OR CYCLOTERPENIC ALCOHOLS AND THEIR HALOGENATED, SULPHONATED, NITRATED OR NITROSATED DERIVATIVES (1) Menthol, a secondary alcohol which is the main constituent of peppermint oil. Crystals; used as an antiseptic, as a local anaesthetic and for the relief of nasal (or rhinal) congestion. (2) Cyclohexanol, methyl- and dimethylcyclohexanols are compounds with a characteristic odour resembling that of camphor. They are used as solvents for varnishes. Dimethylcyclohexanol is used in soap-making. (3) Sterols, or sterins, alicyclic alcohols, saturated or unsaturated, are derivatives of the hydrocarbon perhydro-1,2-cyclopentanophenanthrene, with a hydroxyl group attached to the carbon in position 3, methyl groups on the carbon atoms in positions 10 and 13 and a side chain of 8 to 10 carbon atoms attached to the carbon in position 17. They occur widely in both the animal kingdom (zoosterols) and the vegetable kingdom (phytosterols). The most important is cholesterol, obtained mainly from the spinal cord of cattle and from wool grease; it is also obtained from bile and as a by-product in the extraction of lecithin from egg yolk. Cholesterol is in the form of lustrous, colourless tablets, insoluble in water. The heading excludes ergosterol, found in fungi (mushrooms) and in ergot, a provitamin from which vitamin D2 is obtained by ultraviolet irradiation. Ergosterol and vitamin D2 fall in heading 2936. (4) Inositols, or hexahydroxycyclohexanes, constituents of body tissues. There are nine isomeric forms of inositol. White crystals. Widely distributed in the vegetable and animal kingdoms. (5) Terpineols, very important alcohols, used as a base for perfumes or scents with a lilac odour, etc. They occur in nature, either in the free state or as esters, in many essential oils (e.g., of cardamom, sweet orange, flowers of the orange tree, sweet marjoram, nutmeg, turpentine, cherry laurel, camphor). Technical terpineol is usually a mixture of isomers, but it nevertheless falls in this heading (see Note 1 (b) to Chapter 29). It is a colourless oily liquid, sometimes used as a bactericide. The solid isomer is used in medicine and may also be used as a bactericide. (6) Terpin, obtained by synthesis. White crystals. Terpin hydrate is obtained from turpentine; fragrant colourless crystals. Used in medicine and for the preparation of terpineol. (7) Borneol (Borneo camphor), the alcohol corresponding to the ketone camphor. Its appearance and odour resemble those of natural camphor; a white or sometimes brownish crystalline mass; volatile at ordinary temperature.

28 (8) Isoborneol, plate crystals; intermediate compound in the process of converting α-pinene into camphor. (9) Santalol, the main component of sandalwood oil. (B) Aromatic alcohols and their halogenated, sulfurized, nitrated or nitrogenated produced aromatic alcohols contain a hydroxyl (-OH) group associated not with aromatic rings but with side chains. (1) Benzyl alcohol (phenylmethanol, phenylcarbinol). It is contained in a free state or in the form of esters in jasmine and tuberose oils, in sterix and Toluan balm. Colorless liquid with a pleasant aromatic smell; used in organic synthesis and in the preparation of varnishes, dyes, artificial fragrances, etc. (2) 2-Phenylethanol (phenylethyl alcohol). A liquid that is the main component of rose oil. (3) 3-Phenylpropanol (phenylpropyl alcohol). It is found in sterix, in the benzoin of Sumatra's camedy, in casium oil and in Chinese cinnamon oil; it is a thick colorless liquid with a faint odor of hyacinth. (4) Cinnamon alcohol. It is found in liquid sterix and in Peruvian balm. Crystallizes, forming needle crystals with the smell of hyacinths. (5) Diphenylmethanol (diphenylcarbinol, benzhydrol). Crystallizes in the form of squirrel crystals. (6) Triphenylmethanol (triphenyl carbinol). Crystals. This alcohol is the starting substance for obtaining an important group of dyes, which includes aurine, rosaniline, etc. In this heading, aldehyde bisulfite and ketonbisulfite with combination are considered as sulfonated derivatives of alcohols. This heading also includes metal alcohols of cyclic alcohols.
