查询词典 azoxybenzene

Meanwhile, Azoxybenzene was also detected by GC-Mass from the extracts of culture fluids with dichloromethane, which conformed the probability of the existence of two metabolites: nitrosobenzene and N-phenylhydroxylamine. Because Azoxybenzene might be yield from the reaction of these two compounds under the catalytic influence of alkali.

另外通过GC-MS测定硝基苯降解液的二氯甲烷提取物，测到氧化偶氮苯的存在，它能在碱的催化作用下由亚硝基苯和N-苯基羟胺反应生成，所以它的存在从反面证实了降解中间产物亚硝基苯和N-苯基羟胺的存在。

The experimental results from cyclic voltammetry and constant-potential electrolysis show that the mechanism of the reaction was two molecules and three steps electrochemical process with eight-electrons transferred: anion radical arose in the first step; two-electrons were transferred in the second step and accompanied with coupling reaction of radicals and protonation and dehydrate, the main product was azoxybenzene; two-electrons were transferred in the third step, and azobenzene was achieved.

研究结果表明，硝基苯在铂电极上的电还原反应为双分子八电子三步骤电化学过程：第一步反应为准可逆单电子转移步骤，产生阴离子自由基；第二步为二电子转移步骤，并伴有随后的双分子不可逆自由基偶合反应和快速质子化及脱水反应，主要产物为氧化偶氮苯；第三步是二电子转移产生偶氮苯的过程。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
