Kinetics of the Addition Reaction of Carbon Tetrachloride with Styrene

The kinetics of the addition reaction of carbon tetrachloride with styrene was investigated in the presence of immobilized cuprous chloride catalyst.As the CuCl / carbon nanotuble catalyst with the particle size of 10-8~10-7m was used and the stirring rates of the reaction were kept over 210 r·min-1,both the effects of internal and external diffusion could be ignored,and the reaction was controlled only by the kinetics of the addition reaction.The kinetic model,-rA=K + k1,was established based on free radical addition reaction mechanism and the assumption of single active site adsorption,which agrees well with the kinetic data measured in the temperature range of 65℃ to 75℃.The kinetic parameters were obtained by non-linear fitting,and the activation energy of the dissociative adsorption,which is the control step of the addition reaction,is 1.11×105 kJ·mol-1.The results obtained in this study are useful for the explanation of the addition reaction and the development of its industrial process.
