Benzotrichloride, also known as trichlorotoluene is an organic compound with the formula C6H5CCl3. It is principally used as an intermediate in the preparation of other chemical products such as dyes.[1][2]
Production and uses
Benzotrichloride is produced by the free radical chlorination of toluene, catalysed by light or radical initiators such as dibenzoyl peroxide. Two intermediates are observed:
Benzotrichloride is hydrolysed to benzoyl chloride:[3]
- C6H5CCl3 + H2O → C6H5C(O)Cl + 2 HCl
It is also transformed into benzotrifluoride, a precursor to pesticides:
- C6H5CCl3 + 3 KF → C6H5CF3 + 3 KCl
