溴化锂制备

1.中和法氢氧化锂与氢溴酸进行中和反应，反应液经脱色、过滤、浓缩滤液、过滤、浓缩、结晶、分离，制得溴化锂粒状粉末成品。其反应方程式如下：

2.溴化铁法将铁屑与溴素作用生成溴化铁，再以碳酸锂与溴化铁作用制得溴化锂。该法工艺较为繁杂，容易造成溴化锂损失而降低收率。 3.将纯净的碳酸锂溶解于氢溴酸溶液中，蒸发至干，除净CO2和水分，即得溴化锂。

如果要制得特别纯净的溴化锂，则可进行再结晶数次，除去大部分杂质。具体操作如下：将氢溴酸加入LiBr溶液中使溴化锂沉淀。通入氮气同时加热上述溶液和沉淀以除去过量的酸。在氮气氛围下将沉淀滤出。利用溴化锂在不同温度下，在水中溶解度的较大差别进行再结晶，重复再结晶4～5次。最后在铂容器里，氮气氛围中160℃保持7天以上，将这样的精制溴化锂封入玻璃管中保存。

4.制法先将碳酸锂配制成55%～60%的溶液，加热并不断搅拌下慢慢加入稍过量的45%的氢溴酸进行反应：

反应结束后，滤去不溶物，将滤液加热浓缩至出现少量结晶，停止加热，冷却结晶，待结晶完全后，分去母液，干燥脱水，即可得成品。母液可重新浓缩、结晶。
