The Study on the Synthesis of 3,5-dichloronitrobenzene |
ZHAO Hui etc. (Nanjing Science & Technology University; Nanjing Jiangsu; 210094; China) |
Abstract:dichloronitrobenzene was synthesized from 2,6-dichloro-4-nitroaniline through diazo-reaction and denitrogenation reaction. The yield of 3,5-dichloronitrobenzene is above 60%. Many factors such as amounts and concentration of sulfuric acid, reaction temperature, reaction time, and catalysts were studied. |
Key words:dichloronitrobenzene; Diazo-reaction; denitrogenation |
