production method | is obtained by diazotization and substitution of 2, 6-dinitroaniline. Add sodium nitrite to concentrated sulfuric acid, stir, heat to 70 ℃, after all is dissolved, cool the solution to 25-30 ℃. Slowly add the solution prepared by 2, 6-dinitroaniline and glacial acetic acid, control the adding speed, and make the reaction temperature above 40 ℃. After adding, stir at 40 ℃ for half an hour. Then add the pre-cooled cuprous chloride concentrated hydrochloric acid solution, the reaction is exothermic, and bubbles are generated. When the reaction becomes mild, the bubble is stopped after heating to 80 ℃ for 20min. Add equal volume of water, cool, filter, wash, dry, recrystallize with acetic acid to obtain 2, 6-dinitrochlorobenzene. The yield is about 70%. |
