| Abstract: | 3,5-dichloronitrobenzene(DCNB) was prepared from 2,6-dichlor-4-nitroaniline.then through orthogonal test 3,5-dichloroaniline can be obtained reacting with Na2S by re duction 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%. |
