摘要
在汞盐和硝基苯磺酸存在下,用硝酸硝化甲苯,获得了对位异构体含量较高的-硝基甲苯,对位体和邻位体的比值(p/o=2.41)明显高于汞盐负载在Nafion-H上的催化硝化结果(p/o=1.81)。探讨了汞盐和硝基苯磺酸催化甲苯硝化机理。
The nitration of toluene with nitric acid catalyzed by mercury (Ⅱ) salt and nitro benzene sulfonic acids gave mononitrotoluene of the high para-isomer content. The para:ortho ratio (2.40) was higher than that of mercury (Ⅱ)-promoted nitration of toluene over Nafion-H catalyst (1.81). The mechanisms of the catalytic nitration of toluene were discussed.
