清洁硝化工艺的研究与发展

Study and Progress of Clean Nitration Technology

介绍了当前研究开发中的几种芳烃的清洁硝化工艺,包括液相硝化和气相硝化。这些反应通过改变硝化剂和使用相应的催化剂和介质,不仅成功地避免了浓硫酸的使用,而且提高了原子经济性,具有良好的环境效益。最后探讨了这些新型硝化工艺的发展前景。

This paper studies some clean process used for the nitration of aromatic hydrocarbon,including liquid phase reaction and gas phase reaction. By the use of new nitrating agent,catalysts and solvents,all the reactions eliminate the use of concentrated sulfuric acid and are environmental friendly with high atom economy. Reasearch and development direction of clean nitration reactions are also presented.
