Uses and applications

What the substance is used for, by industry and function

Chem intermediate for benzoyl chloride, dyes-eg, vat yellow 2 & basic green 4, benzotrifluoride (pesticide & drug intermediate), 4-alkoxy-2-hydroxybenzophenone UV stabilizer, ion-exchange resins (former use) & benzoic acid. (Former use).

In organic syntheses (source of benzenyl group).

Benzotrichloride is used to make benzotrifluoride, hydroxybenzophone, pharmaceuticals, and antimicrobial agents.

Used extensively as an intermediate.

Benzotrichloride is used extensively in the dye industry. Benzotrichloride is also used in the manufacture of benzoyl chloride, chlorinated toluenes, and benzotrifluoride and as a dyestuff intermediate.

Roles

  • aetiopathogenetic role
  • carcinogenic agent

Pharmacology

Benzotrichloride is an oily, unstable, colorless, chlorinated hydrocarbon with a penetrating odor. Benzotrichloride is used extensively as a chemical intermediate in industry for the preparation of dyes. Its derivatives are used as UV stabilizers in plastic and to manufacture antiseptics and antimicrobial agents. In the presence of moisture, its hydrolyzed vapors (benzoic acid and hydrochloric acid) are highly irritating to the skin and mucous membranes in humans. Benzotrichloride is reasonably anticipated to be a human carcinogen. (NCI05)

How it is made

/It is/ produced by chlorination of boiling toluene in presence of light and of 2% phosphorus trichloride.

/Produced by/ a process of chlorinating toluene in a series of cascade reactors exposed to mercury dip lamps to provide continuous production of benzotrichloride with less than or equal to 0.2% benzal chloride in the final product.
