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.

邻苯二甲酸二甲酯或二苯醚等与磷酸三丁酯的混合溶剂中环氧化的选择性较高，但由于溶剂对催化剂的配位作用抑制了催化剂的活性，苯乙烯转化率很低；当部分的邻苯二甲酸二甲酯或二苯醚被甲苯取代后，苯乙烯的转化率提高，生成环氧苯乙烷的选择性不变。

Benzyl isopropyl ether also forms CCT complex with oxygen on the benzene ring like phenyl isopropyl ether, but it is easy to oxidize since charge transfer and 〓 transfer may occur at the methylene group adjacent to the benzene ring, which result in the oxidation of the methylene group.(4) The 〓-CCT complex and the initial dark oxidation mechanism of poly were studied.

虽然苄基异丙醚也以苯环与O〓形成CCT复合物，但它却容易发生暗氧化，这是由于与苯基相连的是亚甲基，此时电荷转移发生在苯环与亚甲基之间，引起亚甲基的氧化，而不是异丙基的氧化。

It was confirmed that the 〓-CCT of phenyl isopropyl ether is formed on the benzene ring rather thanon the etheroxy bond. The 〓-CCT complex is not strong enough to induce charge transfer and converts to CTC because the isopropyl group is separated from the benzene ring by oxygen atom. As a result,〓 can not transfer from isopropyl to form radical in cage. Therefore phenyl isopropyl ether is difficult to undergo dark oxidation.

这是由于苯基异丙醚和异丙醚形成O〓-CCT的部位不同，苯基异丙醚的O〓-CCT形成在苯环上，与异丙基相隔一个氧原子，不足以诱发异丙基电荷转移而转化为CTC，也就不能有氢质子转移和笼式自由基的形成，因此难于发生暗氧化反应。
