Phenol

Benzene Phenol, Carbolic Acid, Creosote; a substance obtained from amido benzene, etc., and occurring already formed in Castoreum and in the urine of herbivora. It is a colorle , crystalline ma , which gradually PHENOL ATE acquires a reddish color, and deliquesces on exposure to the air. It melts at 420 C. and boils at 1830 C.; its sp. gr. at o° is 1.084. It po e es a characteristic odor, burning taste, and poisonous and antiseptic properties. It is slowly soluble in water, readily so in alcohol and ether. In a general sense the word is applied to the homologous series of which phenol or carbolic acid is the first member. The phenols are compounds formed from benzene and its homologues by the substitution of hydroxyl for hydrogen in the benzene nucleus. They correspond to tertiary alcohols, as they contain the group COH, and all have weak acid properties. They may be monatomic, such as ordinary phenol, cresol, etc.; diatomic, as pyrocatechin, resorcin, hydroquinone; or triatomic, as pyrogallol, phorglucol. P. -blue, a paste-like substance of blue color. See Pigments, Conspectus of. P. -camphor, camphor combined with carbolic acid. P. Colors. See Pigments, Conspectus of. P.
