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。

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。
