【Abstract】 To provide the kinetic support for the isomerization of o-dichlorobenzene in the industry,the reaction kinetics of o-dichlorobenzene in the presence of AlCl₃ and AlCl₃·6 H₂O was studied. Without internal and external diffusion,the influences of speed,the proportion and amount of catalyst and reaction temperature on the conversion of o-dichlorobenzene were investigated. The optimal reaction conditions were as follows: speed 300 r/min,catalyst dosage 15%（ mass fraction）,AlCl₃ and AlCl₃·6 H₂O mole ratio 2∶ 1,temperature 160 ℃. The kinetics parameters of o-dichlorobenzene isomerization were measured by fitting the experimental date with Kd method. By comparing the experimental and calculated values,the kinetic equation of this reaction is reasonable and can be used for simulation.更多还原
