Chlorobenzene

 

a colorless liquid, with a characteristic odor and a boiling point of 131.7°C. Chlorobenzene is practically insoluble in water but is soluble in many organic solvents.

In industry chlorobenzene is produced by the catalytic chlorination of benzene, carried out at 75°–85°C using metallic iron as the catalyst. It is used in the production of phenol, 4,4′-dichlorodiphenyltrichloroethane (DDT), and intermediate products during the synthesis of dyes. It is also used as a solvent in laboratory work.

Heptachlor epoxide was correlated with cis-chlordane, and several chlorobenzene related compounds (1,2,3,4-TeCBz, PeCBz, and PCA) had weak but nonsignificant (P = 0.05-06) relationships with 1,2,4,5-TeCBz and [alpha]-HCH; oxychlordane was not correlated with any other OCPs (Table S9B).
However, the relationship between [H.sub.2]S and plant chlorobenzene stress tolerance remains poorly characterized, and whether or not oxidation reactions are involved in the process is not clear.
