Alkylation of phenol was used to research catalytic activity of Y/MCM-41. The results have shown that Y/MCM-41 has higher catalytic activity than the traditional Y and MCM-41. For the Y/MCM-41, not only the conversion of phenol raised with tert-butyl alcohol and reaction temperature raising, but also Useful time of Y/MCM-41 was longer. For the Y/MCM-41, the conversion of phenol raised with reaction time raising, But that increased slowly after 3 hours.

In this thesis, this system is used for epoxidation of propylene and styrenewith good results. The solvent effect is investigated for epoxidation of styrene. In the mixedsolvent of dimethyl phthalate / TBP or phenyl ether / TBP, the selectivity for styreneoxide is good but the conversion of styrene is low due to the coordination to thecatalyst of the solvent. When part of dimethyl phthalate or phenyl ether is replacedby toluene, the conversion increases and the selectivity keeps constant.
