説明
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.

fine purple fibres
使用
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.
一般的な説明
Long needles or fine, light purple fibers.
空気と水の反応
2,4,6-Trichloroaniline may be sensitive to exposure to light and air. Insoluble in water.
反応プロフィール
2,4,6-Trichloroaniline is incompatible with acids, acid chlorides, acid anhydrides, chloroformates, and strong oxidizing agents. .
火災危険
Flash point data for 2,4,6-Trichloroaniline are not available. 2,4,6-Trichloroaniline is probably combustible.
安全性プロファイル
Moderately toxic by ingestion.Irritant. Questionable carcinogen with experimentalcarcinogenic data. Mutation data reported. When heatedto decomposition it emits very toxic fumes of Clí andNOx.
純化方法
Crystallise the aniline from ligroin. The benzoyl derivative has m 174o (from EtOH). [Beilstein 12 H 627, 12 IV 1281.]
