| 摘 要： | 在水溶液中，有ＮａＢｒＯ３和ＨＢｒ与强碱离子交换树脂反应，制备了具有良好稳定性的载溴树脂，该树脂于室温下，在ＣＨ３ＯＨ和ＣＨ２Ｃｌ２溶液中，在ＣａＣＯ３存在下，有效地溴化芳胺为溴代芳胺化合物，得到较好的产率，同时探讨了甲醇在反应中的作用。

| Abstract: | The bromine - supported resin was prepared by sodium bromate and hydrobromic acid reacting with strong basic resin in water. The aromatic amines were bromized to give bromo- substituted aromatic amines using the bromine - supported resin in dichloromethane - methanol containing calcium carhonate powder at room tempture, and it gave a good yields. The effect of methanol in the reaction was also discussed. |
