and a pull rod with one end extending into the closed reaction vessel; metal copper is arranged at the end of the pull rod extending into the closed reaction vessel; and the pull rod draws and controls the metal copper to extend into or divorce from the nitric acid level in the closed ...
When nitric oxide (NO), generated from nitric acid and copper, was reacted with a series of 9,10-substituted anthracenes, only 9,10-dimethylanthracene gave EPR detectable nitroxide radicals, although the expected bicyclic nitroxide arising from cheletropic NO addition across the 9,10-positions ...

1) thin nitric acid reaction 稀硝酸反应1. The paper points out the lack in the copper and thick,thin nitric acid reaction experiment, analyzes the difference in the two experiments, introduces the integrated experiment plant, experimental method and strongpoint. 指出了铜与浓、稀硝酸反应实验的不...
The oxidation of copper by nitric acid is a complex reaction forming various nitrogen oxides of varying stability which depends on the concentration of the nitric acid, presence of oxygen, and other factors. 藉由硝酸來氧化金屬銅是一種複雜的反應,形成各種不同穩定度的氮氧化物,其氧化程度取決於硝酸...
