They have close relationship as the former may provide new ideas and approaches for the later, while the later may be the simulation for the former and gives it helps in degradation products identification and mechanism explanation. It is necessary to choose a suitable system, which has high potential of treating EDs and close relationship to the natural environment, to combine the researches in the two aspects.

Second, plasticizers industry trends: the main production of plasticizer tends to continuous large-scale production, and special plasticizers tend to many varieties, small batch intermittent production; products, traditional, low-cost, security risk phthalate plasticizers are being new, safe but relatively high prices of citric acid ester plasticizers, trimellitic acid plasticizer replaced this trend performance in foreign markets significantly, and domestic prices because of factors, phthalate plasticizers will be substantial use.

二、增塑剂行业发展趋势：生产方面主增塑剂趋于连续化大生产，而特殊增塑剂趋于多品种、小批量间歇生产；产品方面，传统的、廉价的、安全风险大的邻苯二甲酸酯类增塑剂正在被新型的、安全的但价格相对较高的柠檬酸酯增塑剂、偏苯三酸类增塑剂所取代，这一趋势在国外市场表现显著，而国内由于价格因素，邻苯二甲酸酯类增塑剂仍将被大量使用。

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.
