1,2-二溴苯制备

将1mol邻溴苯胺和2.5mol氢溴酸的混合物加冰冷却到0℃,在搅拌下迅速加入1mol亚硝酸钠与125mL水配成的溶液,同时添加碎冰使温度保持在10℃以下,当亚硝酸钠溶液只剩5mL时,用淀粉碘化钾试纸测试,直至最后有过量的亚硝酸时为止。将反应物(重氮盐溶液)注入沸腾的溴化亚铜(0.55mol)-氢溴酸(0.6mol)溶液中,注入速度以维持沸腾为准,约30min加完。此时有很多产物随水汽蒸出,加完后通入蒸汽直至不再有油珠蒸出为止。从物中分出下部油层,用浓硫酸洗涤、水洗涤、5%氢氧化钠洗涤,最后再用水洗一次,加3无水氯化钙干燥,然后进行蒸馏,收集223~225℃馏分,得邻二溴苯。产率约80%~90%。
