Phenols are obtained by replacing one or more hydrogen atoms of the benzene ring with a hydroxyl radical (-OH). Substitution of one hydrogen atom yields monophenols; substitution of two or more hydrogen atoms yields polyphenols. Such substitution, in turn, can be carried out in one or more benzene rings; in the first case, mononuclear phenols are obtained, in the second, polyader phenols. The hydroxyl group can also replace hydrogen in benzene homologues; in the case of toluene, a phenol homolog known as cresol is obtained, in the case of xylene, xylenol is obtained. This heading also includes salts and metal alcohols of phenols or phenol alcohols. (A) Mononuclear monophenols (1) Phenol (hydroxybenzene) (C 6H5·OH). It is obtained by fractional distillation of coal tar or by synthesis. White crystals with a characteristic odor, which become reddish under the influence of light, can exist in solution. Phenol is an antiseptic used in pharmaceuticals. It is also used in the production of explosives, synthetic resins, plastics, plasticizers and dyes. For inclusion in this heading, the phenol must have a purity of 90 % or more by weight. Phenol of lower purity is excluded (heading 2707). (2) Cresols (CH3·C6H4·OH). These phenols are derivatives of toluene and are found in different proportions in coal oil. o-Cresol is a white crystalline powder with a characteristic odor of phenol, blurs, eventually becomes brown; m-Cresol is a colorless or yellowish oily, strongly refractive liquid with the smell of creosote; p-Cresol is a colorless crystalline mass, which under the action of light becomes reddish, and then brownish, has the smell of phenol. For inclusion in this heading, individual or mixed cresoles must contain 95 % or more of cresol by weight, all cresol isomers being taken into account together. Cresoles of lower purity are excluded (heading 2707). (3) Octylphenol, nonylphenol and their isomers. (4) Xylenols ((CH3)2·C6H3·OH). These compounds are phenolic derivatives of xylene. Six isomers are known; they are obtained from coal oils. For inclusion in this heading, individual or mixed xylenols must contain 95 % or more xylenol by weight, and all xylenol isomers taken into account. Xylenols of lower purity are excluded (heading 2707). (5) Thymol (5-methyl-2-isopropylphenol). Contained in thyme oil. Colorless crystals with the smell of thyme; used in medicine, in perfumery, etc. (6) Carvacrol (2-methyl-5-isopropylphenol). Thymol isomer, obtained from oregano oil; viscous liquid with a pungent smell.

30(B) Polynuclear monophenols (1) Naftols (C10H7·OH). Naphthols are phenolic proes and stellar naphthalene. There are two isomers: (a) α-naphthol. Colorless shiny crystalline needles, gray pieces or white powder with an unpleasant smell that slightly resembles the smell of phenol. It is toxic and used in organic synthesis (dyes, etc.); (b) β-naphthol. Shiny colorless flakes or crystalline powder, white or slightly pink with a very faint smell of phenol. β-Nafthol has the same applications as α-naphthol, and is also used in medicine and as an antioxidant in the production of rubber, etc. (2) o-Phenylphenol. (C) Polyphenols (1) Resorcin (m-dihydroxybenzene). Diatomic phenol; crystallizes as tablets or needle crystals; colorless, but turns brown in air. It has a faint smell of phenol. It is used for the production of synthetic dyes and explosives, in medicine and photography. (2) Hydroquinone (quinol, p-dihydroxybenzene). Little shiny flakes. It is used to produce organic dyes, in medicine and photography, or as an antioxidant, mainly for the production of rubber. (3) 4,4'-Isopropylidenediphenol (bisphenol A, diphenylolpropane). White cereal. (4) Pyrocatechine (o-dihydroxybenzene). Colorless shiny crystalline needles or tablets with a faint odor of phenol; used to obtain fa maceutical and photographic products, etc. (5) Hexilresorcin. (6) Heptylresorcin. (7) 2.5-Dimethylhydroquinone (2,5-dimethylquinol). (8) Pyrogallol. Small scales or shiny white crystalline powder, light and odorless; it quickly turns brown in air and under the influence of light; toxic. Used to produce dyes, as an herb, in photography, etc. (9) Floroglucin. Large colorless crystals fluorescent in aqueous solution; used as a reagent in chemical analysis, medicine, photography, etc. (10) Hydroxyhydroquinone (1,2,4-trihydroxybenzene). Microscopic colorless crystals or powder that darkens under light. (11) Dihydroxynaphthalenes (C10H6·(OH)2). A group of ten compounds obtained by replacing two hydrogen atoms in the ring of the naphthalene molecule with two hydroxyl groups. Some compounds are used in the production of dyes. (D) Phenolospyrts These compounds are obtained from aromatic hydrocarbons by substituting one benzene ring hydrogen atom with a phenolic hydroxyl group and another hydrogen atom not in the benzene ring with an alcohol hydroxyl group; thus, phenolospyrts have the properties of both phenols and alcohols. The most important is salicylic alcohol (Saligenin) (OH·C6H4·CH2·OH), a white crystal used in

31 medicine as an analgesic and antipyretic agent (antipyretics).
