发烟硝酸

方法：以发烟硝酸代替文献报道的浓硝酸作氧化剂，异喹啉为原料，氧化合成目标产物。

Methods : Isoquinoline as material was oxidized with fuming nitric acid instead of the reported concentrated nitric acid to synthesize target compound .

用阳极氧化法可以在不添加氧化剂和不使用发烟硝酸的情况下，将NO3~-插入石墨纤维中，降低石墨纤维的电阻率。

Under no adding oxidant and no using fuming nitric acid , nitric acid can be intercalated into graphite fiber by anodic oxidation method , thus the electrie resistivity of the graphite fiber will be decreased .
