摘 要: 实验研究了有机废气中的 1.1-二氯乙烯 (CH2 =CCl2 )在 10 1.3kPa和 2 88~ 30 8K下气相臭氧氧化降解过程及其反应动力学。结果表明 ,总的反应级数是 2级 ,相对于臭氧和二氯乙烯浓度均为 1级 ,反应速率常数可用方程Arrhenius(k2=8.32exp[-389.7/T] ) The degradation of vapor phase ozonization of 1.1-dichloroethy-lene in off-gas and its reactive kinetics are studied experimentally at 101.3 kPa and 288~308K. the results indicate that the overall kinetics is the second order and the first order in the concentrations of ozone and 1.1-dichlo-roethylene relatively. The relationship between the reaction rate constant and the temperature can be expressed by the equation below: K 2=8.32 exp.
