| 摘 要： | 对五氧化二氮(N2O5)的制备、放大生产以及N2O5硝化体系的应用进行了综述。其中N2O5/硝酸体系的硝化能力强,但硝化选择性差,故常用于钝化底物的硝化。N2O5/有机溶剂体系硝化温和,选择性好,主要用于酸敏性和水敏性及含多官能团物质的选择性硝化。N2O5/固体载体体系不仅具有N2O5/有机溶剂体系的硝化特点,而且硝化反应在载体表面进行,避免了大量使用有毒的有机溶剂,操作简单,产物易分离。附参考文献30篇。

| Abstract: | The experimental and pilot-plant-scale preparation of dinitrogen pentoxide(N2O5) and three nitration systems based on it were reviewed with 30 references.N2O5/nitric acid system is a very powerful nitration reagent and particularly valuable for the nitration of highly deactivated aromatics.N2O5/organic solvent system is a much milder and more selective nitration reagent,which is well suited for the cases that the substrates or products are sensitive to acid or water,and for regioselective O-nitration.N2O5/s... |
