【Abstract】 The liquid phase autoxidation activity and mechanism of o-chlorotoluene(OCT) and p-chlorotoluene(PCT) in self medium were studied in this paper. The results show that after short induction period, the autoxidaiton rate of both OCT and PCT increased to maximum. However, only the rate of OCT kept constant, the rate of PCT decreased rapidly, which is different from the autoxidation rate of OCT and PCT in the medium of acetic acid. The paper discussed the reason of the abnormal autoxidation activity and presented a method of increase the PCT autoxidation rate.更多还原
