2,4,6-Trichloroaniline Chemical Properties,Uses,Production
Description
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.
Chemical Properties
fine purple fibres
Uses
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.
General Description
Long needles or fine, light purple fibers.
Air & Water Reactions
2,4,6-Trichloroaniline may be sensitive to exposure to light and air. Insoluble in water.
Reactivity Profile
2,4,6-Trichloroaniline is incompatible with acids, acid chlorides, acid anhydrides, chloroformates, and strong oxidizing agents. .
Fire Hazard
Flash point data for 2,4,6-Trichloroaniline are not available. 2,4,6-Trichloroaniline is probably combustible.
Safety Profile
Moderately toxic by ingestion.Irritant. Questionable carcinogen with experimentalcarcinogenic data. Mutation data reported. When heatedto decomposition it emits very toxic fumes of Clí andNOx.
Purification Methods
Crystallise the aniline from ligroin. The benzoyl derivative has m 174o (from EtOH). [Beilstein 12 H 627, 12 IV 1281.]
