Benzotrichloride is a chemical compound selected from the group consisting of aromatic chlorinated hydrocarbons. It is a colorless, pungent-smelling fluid.

Production and representation

Benzotrichloride is obtained by chlorination of toluene to give, for example, dibenzoyl peroxide, can be used as a catalyst.

Properties

Benzotrichloride is a colorless, pungent-smelling liquid that is very poorly soluble in water. The vapors of benzotrichloride are 6.75 times heavier than air.

Use

Benzotrichloride is used only as an intermediate product for the preparation of benzoyl chloride, benzotrifluoride ( starting material for herbicides, dyes, pharmaceuticals), dyes, and 2,4-dihydroxybenzophenone.

Safety

Benzotrichloride is included in the rule Rule 905 as carcinogenic category 2.

Proof

Benzotrichloride can be determined in air by gas chromatographic determination using Flammenionsationsdetektor.
