摘要：

The chemical kinetics of the chlorination of low concentrations of biphenyl dissolved in water are presented. The pH range investigated was 6.2 to 9.0, in which range the chlorinating agent is molecular hypochlorous acid and its dehydration product, chlorine monoxide. The reactions in the neutral and alkaline ranges produced two monochlorobi-phenyls, o- and p-chlorobiphenyl, with a 1/2 o:p ratio of 0.8. Second-order dependence upon undissociated hypochlorous acid concentration and first-order dependence upon biphenyl concentration were observed. Reaction rate constants and activation energies were determined. Moderate ionic strength variations and potential metallic catalysts had no measurable influence on reaction rate. It was found that acid catalysis occurs below a pH of 6.2, where highly reactive molecular chlorine is present. © 1979, American Chemical Society. All rights reserved.
