Brit. /ˈanᵻliːn/, /ˈanl̩iːn/, /ˈanᵻlʌɪn/, /ˈanl̩ʌɪn/, /ˈanᵻlɪn/, /ˈanl̩ɪn/, U.S. /ˈænəˌlaɪn/, /ˈænələn/
Etymology: < (by Fritzche 1841) anil n. indigo + -ine suffix1.
Brit. Chem.
1. A chemical base important in the arts as the source of many beautiful dyes; obtained originally by distilling indigo with caustic potash, but subsequently from many other sources, especially coal-tar.
A. is a colourless, oily, aromatic, volatile liquid, of constitution C6H5(NH2), which may be viewed as ammonia in which one hydrogen atom is replaced by the compound radical phenyl C6H5, hence also called phenylamine; or as benzol C6H6, in which one atom of H is replaced by amidogen NH2, whence also called amidobenzol and amidobenzene. It forms crystalline salts with acids, e.g. aniline acetate, aniline oxalate, aniline sulphate, aniline nitrate, etc., and compound anilines in which one or both the hydrogen atoms in NH2 are replaced by radicals, as ethylaniline, diethyl-aniline, etc.
