Beschreibung
Trichloroaniline is particularly important as a chemical intermediate in manufacturing many benzene derivatives and other organic compounds. For instance, 2,4,6-trichloroaniline is an essential precursor of 1,3,5-trichlorobenzene. The latter has been extensively studied and developed for insecticides and fungicides. It, in turn, is a precursor of trichlorodinitrobenzene, which is especially important in combatting crop diseases and is an intermediate for dyestuffs. In military applications, 2,4,6-trichloroaniline is utilized for the preparation of insensitive energetic material that is employed in several Navy weapons systems. The synthesis of 2,4,6-trichloroaniline has almost invariably been accomplished by chlorinating aniline with chlorine or sulfuryl chloride.

Verwenden
2,4,6-trichloroaniline is important as an intermediate in the manufacture of benzene derivatives, including 1,3,5-trichlorobenzene and is useful in the formation of fungicides, mono-azo dyestuffs, and the preparation of hexachlorodiphenyl urea.
Tetrachloronitrobenzene was prepared from 2:4:6-trichloroaniline,which was converted by a Sandmeyer reaction into 1:2:3:5- tetrachlorobenzene.
Allgemeine Beschreibung
Long needles or fine, light purple fibers.
Air & Water Reaktionen
