Anilinium chloride is a chemical compound from the aminobenzenes group and the most important salt of aniline .

Extraction and presentation

Anilinium chloride can be obtained by reacting aniline and hydrochloric acid .

properties

Anilinium chloride is a flammable, difficult to ignite, white solid in the form of leaves or needles, which is easily soluble in water. In aqueous solution, anilinium chloride is largely hydrolytically split. It has a monoclinic crystal structure with the space group Cc (space group no. 9) . Template: room group / 9

use

Anilinium chloride is often used instead of aniline in syntheses, e.g. B. in the production of phenyl isocyanate from aniline and phosgene , as well as for the synthesis of various aniline intermediates and dyes.
