benzenemethanol. C 7 H 8 O(108.13). C 6 H 5 CH 2 OH. It exists naturally in many flower essential oils, such as jasmine, ylang-ylang, and acacia, either free or in the form of esters of acetic acid, benzoic acid, and cinnamic acid. It can be synthesized by hydrolysis of benzyl chloride, reduction of benzaldehyde, or the Cannizzaro reaction. Aromatic liquid. Melting point -15.3 °C, boiling point 206 °C. 1.0493. 1.5426. Soluble in many organic solvents, including alcohol and benzene, and slightly soluble in water. It is gradually oxidized by oxygen in the air to produce benzoic acid via benzaldehyde. It is used as a fragrance for cosmetics and soaps, and is widely used in the fragrance industry as a fixative for blending jasmine and other fragrances. It is also used in the preparation of injections, as it has local anesthetic and antiseptic properties.
