3-NITROBIPHENYL - Reference Information
| use | organic synthesis intermediate. |
| Production method | m-nitroaniline is diazotized with sodium nitrite below 0 ℃, and then reacted with dimethylamine to prepare 1-m-nitrobenzene -3, 3-dimethyltriazene (melting point 100.8-101.5), heated and refluxed with benzene, and added a benzene solution of toluene sulfonic acid dropwise under intense stirring. At the end of the reaction, water is added to layer, the organic layer is washed with water, alkali washed, dried, benzene is distilled, and the fraction at 115-118 ℃(13.3Pa) is collected to obtain 3-nitrobiphenyl. |
