Regioselectivity and composition of the green nitration products between methyl salicylate and iron(ⅲ) nitrate 硝酸铁与水杨酸甲酯绿色硝化的选择性及其副产物组成的研究
When the sample solution was irradiated with an ultra-violet lamp, the deeoloration rate of the methyl orange solution was directly proportional to the concentration of nitrate and nitrite. 在紫外光照射下甲基橙退色程度与硝酸盐和亚硝酸盐含量成正比。

Poly ( methyl methacrylate) ( PMMA) was chosen to wrap alumina siloxane sol which was formed by water glass, aluminum nitrate and α methacrylic acid; therefore, alumina siloxane gel wrapped by PMMA was obtained. 用聚甲基丙烯酸甲酯(PMMA)对由水玻璃、硝酸铝和α甲基丙烯酸形成的硅铝氧烷溶胶进行包裹,得到PMMA包裹的硅铝氧烷凝胶。
The graft copolymers of silk sericin and methyl methacrylate were synthesized by using ceric ammonium nitrate as initiator in acidic aqueous medium. The graft copolymers were characterized by~ 1H NMR, IR, SEM and GPC. 在酸性水介质中,以硝酸铈铵为引发剂合成了丝胶-甲基丙烯酸甲酯接枝共聚物,其结构经1HNMR,IR,SEM和GPC表征。

Finally, paper takes the decomposing explosion of methyl nitrate as an example to illustrate how to use this approach to quantitatively evaluate the potential dangers in such exothermic reaction system with possibility of thermal explosion. 用硝酸甲酯分解爆炸实例,说明如何利用安全指数对具有热爆炸可能性的系统的潜在危险性进行定量评价,其预测结果与实验结果一致。
The results indicated that the nitration process began with the formation of coordination complexes of copper with methyl salicylate, which then activated the nitrate group to liberate oxygen and nitroxyl radical. 结果表明,该硝化过程首先形成了水杨酸甲酯铜配合物,从而使硝酸根得到活化,形成氧自由基和硝基自由基。
