They are also employed in pesticide formulations (the highest consumption of monochlorobenzene in the US). 5. p-Bromophenyl chloride. Chlorobenzene has been identified as one of various halocarbons emitted in volcanic gases. Chlorobenzene is produced by chlorination of benzene in the presence of a catalyst, and is produced as an end product in the reductive chlorination of di- and trichlorobenzenes. It is one of the leading sources for all commercial real estate needs. EPA has classified chlorobenzene as a Group D, not classifiable as to human carcinogenicity. Chlorobenzene biodegrades slowly in soil and aquifer material(6). Other biological screening tests have observed slow biodegradation(10). At one time, chlorobenzene was the main precursor for the manufacture of phenol: C 6 H 5 Cl + NaOH C 6 H 5 OH + NaCl The reaction also has a byproduct of salt.
