碘化铝 [7784-23-8] 制备方法及用途

制备方法

1.将铝屑与少量碘结晶装入充满二氧化碳的烧瓶中,加热反应。进一步加入碘至残留的少量铝中。使反应生成物在熔融状态下保持一段时间,在氮气流中移至蒸馏烧瓶。用真空泵进一步减压,缓缓蒸馏。为了保护真空泵,使气体经过两个充满活性炭的洗气瓶以除去碘蒸气。2.将干燥及升华过的碘20g溶于80mL二硫化碳中,溶液与3.5g的薄铝片一起装入带有回流器的烧瓶中,进行加热。反应结束时,将混合物过滤分离,滤液在水浴上加热蒸馏,以除去大部分二硫化碳。令浓缩后的残余物冷却,即析出碘化铝结晶。将结晶吸滤分离,用己烷洗涤,在100℃下干燥。生成物带有黄褐色。

碘化铝 [7784-23-8] 物化性质

外观与性状:
粉末
密度:
3.98 g/mL at 25 °C(lit.)
熔点:
191 °C(lit.)
沸点:
360 °C(lit.)
闪点:
360°C
存储条件/存储方法:

干性的保护气体下处置,

保持贮藏器密封

放入紧密的贮藏器内,储存在阴凉,干燥的地方

稳定性相关:

如果遵照规格使用和储存则不会分解

避免接触光,水分/潮湿,空气

吸湿性极强,在空气中发烟,加热即分解为碘及氧化铝。在真空中仅升华而不分解。可溶于二硫化碳、乙醇、乙醚。可与四氯化碳、联氨、光气等激烈反应。从液氨可制得AlI3·xNH3等溶剂合物。除此外,也可与硫化氢、二氧化硫、膦等生成溶剂合物。
