Pregnana-3, 16, 20-triol was efficiently transformed into pregn-16-ene-3S, 20S-diol diacetate. And then the Pd-catalyzed reaction was reinvestigated.

提供了一种将剑麻皂甙元降解产物孕甾三醇转化为孕甾－16-烯－3S，20S-二醇二乙酸酯的高效合成方法，并重新考察了其钯催化反应。

A part of NAPL-phase pollutant was oxidized during Fenton-like oxidation, However H2O2 was catalyzed to produce O2, an produced air sparging effect. The soil was disturbed, which increasing NAPL dissolution and volatilization. When using the low H2O2 flux to pass through column, the oxidation of MTBE and TPH of 95 gasoline is better than that of high H2O2 flux.

在管柱连续流Fenton-like反应处理95汽油NAPL过程中，NAPL态污染物部份是被氧化，但H2O2被催化产生之O2 扰动NAPL态污染物，因而增加溶出浓度并产生类似air sparging之去除效果。

The coupling reactions of Suzuki between the transitional metal-catalyzed phenylo boric acid and benzene halide and the Suzuki-Type between phenylo boric acid and carboxylic acid derivatives are two kinds of important reactions in constructing C-C bond.

过渡金属催化的苯硼酸与卤代苯之间的Suzuki和与羧酸衍生物之间的Suzuki-Type偶联反应是构建C-C健的两种重要反应。

For the high affinity sites, binding constant decreases with the decrease of the alkyl chain lengh in the surfactants, but for the low affinity sites, binding constant increases and are not distinct when the alkyl chain is dedocyl. The binding sites are related to the alkyl chain lengh, not for the number of hydrophile groups and temperature.Isothermal titration calorimetry has been used to observe the enzyme-catalyzed hydrolysis reaction of urea.

对于高结合位点，结合常数随疏水碳链长度的减小而减小；对于低结合位点，结合常数随疏水碳链长度的减小而增大，相应的当碳链减小至C12时，低结合位点不明显，结合位点数可能只与碳链长度有关，随亲水头基和温度变化不明显。
