Also, very large yields of papain Cys25SSR were produced from the reactions of the radicals and H2O2. In effect, it is apparent that under certain conditions the oxidation of "activated" SH groups of important target molecules could become coupled to the OH or O-2 -initiated oxidation of ...

摘要:研究了异丙醇作为溶剂时,TS–1催化丙烯H2O2环氧化反应过程主副反应动力学,分析 了丙烯压力、温度等因素对反应的影响,发现当温度低于40o C、丙烯压力为0.3 MPa时,环氧丙 烷的收率达到75%,可以采用异丙醇法制H2O2与丙烯环氧化集成.关键词:环氧丙烷;TS–1催化剂;过氧化氢;异丙醇;动力学 中图分类号...
The reactions between FeS2 and H2O2 generate massive Fe2+ ions (Eqs. (1), (2)), then produce numerous OH radicals (Eq. (3)) to degrade organic pollutants. Owing to the produced H+ (Eqs. (1), (2)), FeS2/H2O2 exhibits outstanding oxidation capability in a much wider pH range than ...
Theoretical studies on reactions of the stabilized H2COO with HO2 and the HO2···H2O complex. The reactions of H(2)COO with HO(2) and the HO(2)···H(2)O complex are studied by employing the high-level quantum chemical calculations with B3LYP and C... L Bo,XF Tan,ZW Long,....
The fundamental aspects of electrochemical oxygen reactions are first introduced. Various types of catalysts that can effectively produce H2O2 via two-electron oxygen electrochemistry are then presented. In parallel, the unique structure-, component-, and composition-dependent electrochemical performance ...

近几年来,在无卤液相反应体系中开展非线性化学反应设计、机理和复杂现象研究方面的工作逐渐增加,Jensen振荡反应、O2-S2--SO32--亚甲蓝振荡反应引发人们对无卤非线性反应体系的兴趣,后来设计的其中一个无卤振荡体系过氧化氢-硫氰酸盐-硫酸铜反应在封闭体系和开放体系皆可产生双稳态和振荡现象,Epstein等根据当时的实验...
H2O2 consumption kinetics and mechanism and the effect of diethylenetriaminepentaacetic acid (DTPA) and silicate were investigated. The results showed that the kinetics and mechanism were different for the chromophore removal reactions and the reactions that dominate the total peroxide consumption. This obs...
