Abstract 

By hydrothermal synthesis method, mesoporous molecular sieve SBA-15 was obtained with the template P123, then tin modified mesoporous molecular sieve SO42-/Sn/SBA-15 was obtained by impregnation into solution of tin(IV) chloride pentahydrate, then into sulfuric acid. The infrared spectroscopy(IR), thermogravimetric analysis(TG), scanning electron microscopy(SEM) and transmission electron microscopy(TEM) were used to characterize the structure of the catalyst. The performance of the catalyst was studied by epoxidation of α-pinene. The influence of the molar ratio of SBA-15 and SnCl4·5H2O, the dosage of catalyst and the molar ratio of peroxyacetic and α-pinene were discussed.The results showed that the conversion rate of α-pinene could reach 95.4%, and the yield of 2,3-epoxypinane was 88.82% when the molar ratio of SBA-15 to SnCl4·5H2O was 5:1, dosage of SO42-/Sn/SBA-15 catalyst was 2.5% (α-pinene weight),and the molar ratio of peroxyacetic to α-pinene was 1.2.
