Aniline
Definition:
(n.) An organic base belonging to the phenylamines. It may be regarded as ammonia in which one hydrogen atom has been replaced by the radical phenyl. It is a colorless, oily liquid, originally obtained from indigo by distillation, but now largely manufactured from coal tar or nitrobenzene as a base from which many brilliant dyes are made.
(a.) Made from, or of the nature of, aniline.
