研究了脉冲电晕等离子体反应器结构的变化对乙硫醇消除效果的影响规律。

The observation of distribution of MFI isattributed to preferential adsorption of the ethanethiol molecules in the straight andzig-zag channels.

在相同的温度下，乙硫醇在 MFI 上的吸附量要比在 MOR 沸石上的吸附量大得多，对于MFI 沸石，直型孔道比之型孔道表现出更优良的吸附性能。

The diffusivity of ethanethiol in flexible MOR is higher than that in flexible MFI, because the 12 member ring in MOR is larger than the 10 member ring in MFI.

对比这两种沸石，MOR中的扩散系数要比MFI沸石中大，这是因为乙硫醇分子在MOR12元环中扩散更易进行所致。

And then, the second-order reaction rate constant was K =0.025 L/. The removal of ethanethiol in raw water by potassium permanganate under coagulation condition was poorer than in pure water condition, So predicted concentration of potassium permanganate was lower than real concentration.

高锰酸钾在原水混凝条件下对乙硫醇的去除效果劣于纯水条件下的去除效果，在水中其它有机物与高锰酸钾反应条件下高锰酸钾浓度变化的拟合结果与实际情况存在偏差，是产生差异的主要原因。

This dissertation includes two parts. The first part deals with study on gas-phase reactions of metal ions with ethanethiol molecule by using the laser ablation-molecular beam method and density functional calculations. The second part describes experimental and theoretical study on VUV photoionization of some molecules using synchrotron radiation.

In this study, new benzo[l,2,3]thiadiazole derivatives were designed according to relationship of structure and efficacy. The 9 novel compounds were synsthesized with following reactions. The chlorine atom in 2-chloro-3,5-dinitro-benzoic acid as beginning raw material was substituted by 2-methylpropane-2-thiol, esterified then with bromoethane, reduced by iron powder and cyclized to obtain ethyl benzo[l,2,3]thiadiazole-7 after diazonation reation.

本论文根据苯并噻二唑诱导剂的构效关系设计了新的苯并噻二唑的结构，并合成了9个未见文献报道的化合物，合成步骤如下：采用2-氯-3，5-二硝基苯甲酸为起始原料，苯环上的氯原子被叔丁基硫醇置换，羧酸由溴乙烷酯化，硝基由铁粉还原，随后经重氮化关环生成苯并[1，2，3]噻二唑-7-羧酸乙酯。

In order to improve the catalytic performances of the chloroaluminate, some organic chemicals with strong electron-donating capacity,such as benzene,alkylbenzene,thioalcohol and thiophene,were introduced into the ionic liquids to modify the ionic liquids.
