Brit.

/ˈbɛnziːn/,

/bɛnˈziːn/, U.S.

/ˈbɛnˌzin/,

/ˌbɛnˈzin/

Etymology: < benz- (in benzoic adj.) (acid) + -ene comb. form The name originally given by Mitscherlich in 1833 was benzin or benzine , for which Liebig in 1834 substituted benzol n. See benzine n.

Chemistry.

1. An aromatic hydrocarbon, C₆H₆, the first or simplest member of the benzene series, C_nH_2n—6; a thin, colourless, strongly refracting fluid, volatile and highly inflammable, formed by distilling benzoic acid with lime, and found in 1849 in the more volatile parts of coal-tar; it dissolves fats, resins, gutta-percha, etc. whence it is used for removing grease-spots and cleaning gloves, as well as for illuminating purposes. (See benzoline n.)

1877 H. Watts Fownes's Man. Elem. Chem. II. 419 In the homologues of benzene, the six carbon-atoms belonging to the benzene itself are said to form the benzene-ring, benzene-nucleus, or principal chain, while the groups, CH₃ etc., joined on to these carbon-atoms, are called lateral chains.
