Tetrachloroterephthalic acid was prepared by chlorinating terephthalic acid, oleumsolvent and iodine catalyst. Tetrachloroterephthalic acid was acylated by sulphurous oxychloride in the presence of DMF to form tetrachloroterephthaloyl chloride. The acyl chloride product was fluorinated by potassium fluoride and esterified by methanol to synthesize dimethyl tetrafluoroterephthalate. The ester was reduced with potassium borohydride and lithium chloride to give tetrafluoroterephthalyl alcohol. The above product was bromated in the hydrobromic acid to obtain 4-bromomethyl-2,3,5,6-tetrafluoro-benzene methanol. 4-Methyl-2,3,5,-6-tetrafluorobenzene ethanol was obtained by reducing the bromide with magnesium. In the exist of DCC and DMAP, tefluthrin was got by the condensation reaction between 4-methyl-2,3,5,6-tetrafluoro-benzene methanol and-(1RS,3RS)- 3-(2- chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethyl cycolpropanecar-boxylate acid.

I have finished the ratio calculation of mw materials used to produce cementclinker, relative environmental impact importance assessment of emissions andenvironmental synthetic index under different conditions.the result means that we can selectthe optimal procession parameter and optimal procession ,considering environmentalactor ,mechanic erect kiln is the best one among the different kilns.the procession of closed-loop recyclable concrete is introduced in detail ,we found it is possible to make full use ofwasted concrete illimitedly by proper design ,though the recyclable concrete physicalfunction decreased a little comparing with virgin concrete, it's environmental property ismuch better than usual concrete.we also found that it is possible to use wasted concrete asthe coarse aggregate or fine aggregate.we probe the possiblity that fuzzy mathematics isused to judge whether a product is green product or not.

确定了不同窑型的最佳的工艺操作参数；比较了不同窑型的环境性能，得出结论：预分解窑是最佳的工艺选择。本软件具有专家系统的功能，本软件的最大特点是动态性和灵活性，这是为人为的因素，地方的因素变化性而设计的。允许输入不同的边界条件，即可得到不同的结果，这为水泥-混凝土的环境化设计提供了有力的帮助。本人也努力设计一个适用于水泥厂的数据库的框架，来实现水泥厂的在线评估。本文探讨了实现环境化设计的可再循环的混凝土的设计，得出结论：通过合理设计的混凝土的无限循环是可能的，虽然再循环的混凝土的性能与原混凝土相比有所下降，但其环境性能是普通混凝土无法比拟的，本文还探讨了废混凝土的利用的可能性及评估，废混凝土用作混凝土的粗集料是合适的，虽也可作细集料，但不值得提倡。
