Hazard Information

General Description

Long needles or fine, light purple fibers.

Reactivity Profile

2,4,6-TRICHLOROANILINE(634-93-5) is incompatible with acids, acid chlorides, acid anhydrides, chloroformates, and strong oxidizing agents. .

Air & Water Reactions

This compound may be sensitive to exposure to light and air. Insoluble in water.

Fire Hazard

Flash point data for this chemical are not available. 2,4,6-TRICHLOROANILINE is probably combustible.

Chemical Properties

fine purple fibres

Uses

Tetrachloronitrobenzene was prepared from 2:4:6-trichloroaniline,which was converted by a Sandmeyer reaction into 1:2:3:5- tetrachlorobenzene.

Preparation

2,4,6-Trichloroaniline can be prepared by reaction of dry aniline with chlorine gas while in a anhydrous solution of carbon tetrachloride. 2,4,6-Trichloroaniline precipitates from solution as a white solid. If water is introduced to the solution the white material will polymerize to form aniline black.
Process for the preparation of 2,4,6-trichloroaniline

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.]
