Chemical properties: 1 - Bromo - 2 - nitrobenzene as buff acicular crystal. 43 ℃ melting point, boiling point 261 ℃, relative density 1.6245 (80/4 ℃). Soluble in ethanol, soluble in ether and benzene, insoluble in water.
Purpose: 1 intermediates in organic synthesis. Two pharmaceutical intermediates, also can be in EPA8081A method analysis of organochlorine pesticides in water and soil to internal standard.
Production methods: the adjacent nitroaniline by the following steps. Neighbouring nitroaniline and a mixture of sulfuric acid cooling to 0 to 5 ℃, slowly add sodium nitrite solution under stirring, potassium iodide to the reaction of starch test paper turned blue. Will the diazonium salt solution under stirring slowly add 40 ℃ of cuprous bromide solution. After cooling, were extracted with ether extract with alkali, hydrochloric acid solution and water washing, a quick product after recovery of ethyl ether. The yield of about 70%.
