Aniline is an amine that is used to manufacture dyes. The lactic acid eventually increases the acidity of the brine to a level that kills any harmful bacteria, which require a basic environment. In this case, water would act as a base in which it would accept a proton from C6H5NH3+ to form the hydronium ion H3O+. Aniline can alternatively be prepared from ammonia and phenol derived from the cumene process.

Like other amines, aniline is both a base (pKaH = 4.6) and a nucleophile, although less so than structurally similar aliphatic amines. A compound that can donate protons are considered acids but here in Methanol; as a result, water is a better proton donor, which makes Methanol a weak acid. [24][25] In 1842, Nikolay Nikolaevich Zinin reduced nitrobenzene and obtained a base that he named benzidam. Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) is an organic compound with the formula C 6 H 5 NH 2.Consisting of a phenyl group (C 6 H 5) attached to an amino group (NH 2), aniline is the simplest aromatic amine.It is an industrially significant commodity chemical, as well as a versatile starting material for fine chemical synthesis.
