Abstract: Mesoporous molecular sieves MCM-41 containing Al and Zr were prepared.SO42- and BO33- were incorporated into MCM-41 to get the super acidic SO42-/Al-MCM-41、SO42-/Zr-MCM-41、BO33-/Al-MCM-41 and BO33-/Zr-MCM-41 catalysts, which were characterized by XRD, T-IR measurements and Hammett indicator.Results show that the skeleton of mesoporous molecular and crystallinity were improved.SO42- and BO33- were incorporated into the frame of MCM-41.AlCl3 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 AlCl3 and polarity of solvent.

Key words: mesoporous molecular sieve, catalysis, α-pinene
