This pale yellow solid is one of the three isomers of chloroaniline . Anilin (nach spanisch oder auch arabisch: an-nil = blau = Indigo-Farbe) oder Benzenamin ist eine klare, farblose bis schwach gelbliche, ölige Flüssigkeit mit eigenartigem Geruch, die an der Luft schnell rötlich-braun wird. Es ist ein Benzolring mit einer Aminogruppe (–NH2) und damit ein aromatisches Amin. Mit Säuren versetzt bildet es Anilinsalze. Die basische Wirkung von Anilin wird durch den mesomeren Effekt abgeschwächt, da dieser die Elektronendichte der Aminogruppe ver…
