Kinetics of Low-Temperature Oxidative Chlorination of Benzene in Aqueous Acetic Acid

摘要

The kinetics of chlorination of benzene with a mixture of sodium peroxide with hydrochloric acid in aqueous acetic acid at 298 K was studied.The chlorination rate is the highest when the AcOH concentration in the binary solvent is 49.4-40.6 mol % and the ratio of the initial cocentrations of water and sodium peroxide,18.5-20.2.The linear dependences of log k_(app) on the AcOH concentration and [H_2O]_0/ [Na_2O_2]_0 ratio were obtained.
