三溴化铝制备

可用金属铝或铝化合物法制造。
1.金属铝法将铝加入反应器中，加入溴素进行反应，生成溴化铝，经减压蒸馏制得三溴化铝，其反应方程式如下：

2.氢氧化铝法将氢氧化铝加入反应器中，加氢溴酸溶解反应，生成溴化铝。其反应方程式如下：

图XIII-17 溴化铝制备装置

3.将曾用四氯化碳或其他有机溶剂脱脂及干燥过的铝屑投入烧瓶中。从7导入用五氧化二磷干燥过的氮，从1和4放空。将湿气全部逐出以后，关闭7。使反应器内充分干燥以后，氮气从1到4放空。从滴液漏斗将用浓硫酸干燥过的溴滴入烧瓶6中。滴加的速度应控制在使生成的溴化铝因反应热而在空气冷却管5中回流的程度。即使溴滴加完毕后，也应当有相当过剩的铝。加热反应烧瓶至从5回流的液体为无色。将氮气的流动方向改为从4到1。将装有五氧化二磷的干燥管与1连接，将烧瓶6加热至270℃左右，使溴化铝蒸馏进入收集器2。蒸馏完毕时，在继续通入氮气的情况下，将收集器2从3处拆下，并立即封闭3处。如果无需无色的溴化铝时，制备操作可在装有溴滴液漏斗的普通的蒸馏烧瓶中进行。将烧瓶加热至100℃，并滴加溴。其滴加速度应能使溴迅速消耗。温度应该较溴化铝的沸点低。
