Reaction kinetics of diphenylmethane synthesis over immobilized AlCl_3 catalyst

JI Min,WU Hai-ming,HE Min,JIANG Shan,CAI Tian-xiState Key Laboratory of Fine Chemicals,Dalian University of Technology,Dalian 116012,China  
The catalyst of AlCl3 immobilized on γ-Al2O3 with different pores was prepared and tested in the benzylation reaction of benzene with benzyl chloride to form diphenylmethane.Conventional homogeneous pure AlCl3 was also included for comparison especially on temperature.The experimental data of forming diphenylmethane for different reaction temperature and catalyst were gained by gas chromatography.The kinetics model of the reaction,in which internal diffusion factors were considered,was established.Then the parameters of diphenylmethane apparent formation rate constant,apparent activation energy and diffusion coefficient were obtained in a liquid-solid reaction system.The results indicate that the immobilized AlCl3 catalyst was found to be more selective but less active compared to pure AlCl3 due to its pore diffusion resistance.With the decrease of the pore diameter of the supports,the diffusion coefficient of the reaction decreases sharply.The internal diffusion resistance plays an important role in the activity of benzylation reaction of benzene with benzyl chloride to form diphenylmethane over the immobilized AlCl3 catalysts.
