摘要
以2,6-二氯-4-硝基苯胺为原料,先合成出3,5-二氯硝基苯(DCNB),再通过正交实验法经Na2S还原合成3,5-二氯苯胺。确定了该方法的适应条件为:m(DCNB)=2.88 g,n(DCNB):n(Na2S)=1:3.5,回流条件下反应3h,产物产率为70.3%。
3,5 - diehloronitrobenzene(DCNB) was prepared from 2,6 - diehlor - 4 - nitmaniline, then through orthogo- hal test 3,5 - diehloroaniline earl be obtained reacting with Na2 S by re duetion reaction . The optimum reaction m( DCNB ) = 2.88 g , n(DCNB) : n(Na2S) = 1:3.5, refluxing reaction 3uh, the yield amounted to 70.3u%.
