4-氨基-3-硝基苯磺酸的合成反应研究(Ⅲ)

Study on Synthesis of 4-Amino-3-Nitro-Benzenesulfonic Acid(Ⅲ)

本文分别以过量硫酸及发烟硫酸为反应介质 ,对邻硝基苯胺的磺化反应条件进行了研究 ,得出了较佳的反应条件。在此条件下 ,磺化反应的转化率可达 90

The sulfonating techonolgical factors of o -nitro-aniline in the medium of sulfuric acid fuming sulfuric acid were studied in this paper,the percent conversion of sulfonation reaction is more than 90%.
