固体酸催化甲苯选择性硝化研究进展

Advance in Catalytic Nitrification of Tolune by Solid Acid

甲苯一硝化过程采用硫酸做催化剂,从经济和环保意义上考虑,如何替代硫酸且提高产物中对硝基甲苯比例成为非常重要的课题,目前固体酸催化硝化技术研究成为该领域的热点。文章综述了近年来固体酸作催化剂在不同体系下催化甲苯硝化取得的进展,包括这些方法的特点、产生的结果以及存在的问题。

Vitriol is the catalyst in nitrination of toluene.From the economic and environmental sense considering,it is a very important subject to replace of vitriol and increase the ratio of p-nitritolune in products.Nitriation of tolune by solid acid catalysts is the hotspot in the filed at present.The research progress on nitration of toluene by solid acid catalysts in different system was reviewed,concluding the characteristic of the method,results and problem.
