Mesoporous molecular sieves MCM 41 containing Al and Zr were prepared.SO 2- 4 and BO 3- 3 were incorporated into MCM 41 to get the super acidic SO 2- 4/Al MCM 41,SO 2- 4/Zr MCM 41,BO 3- 3/Al MCM 41 and BO 3- 3/Zr MCM 41 catalysts,which were characterized by XRD,FT IR measurements and Hammett indicator.Results show that the skeleton of mesoporous molecular and crystallinity were improved.SO 2- 4 and BO 3- 3 were incorporated into the frame of MCM 41.AlCl 3 was supported on mesoporous molecular sieves to catalyze the polymerization of α pinene .Factors affecting the reaction were discussed in detail,such as:acid intensity of mesoporous molecular sieve,amount of AlCl 3 and polarity of solvent.
