生产制备方法及用途展开↓

制备方法


1.中和法将碘和赤磷加入盛有水的反应器中,在搅拌下进行反应,把反应溶液经仔细过滤后,进行蒸馏,收集125~130℃的馏分,得到氢碘酸,通入氨气使氢碘酸全部被中和至Ph值8~9时,停止通入氨气。把溶液过滤后,进行水浴真空蒸发,直至结晶大部分析出为止。经冷却、离心分离、在50~60℃干燥,制得碘化铵成品。其反应方程式如下:如果成品颜色发黄,可用酒精洗涤处理。将氨气通入氢碘酸中,使氢碘酸全部被中和至pH值为8~9时,停止通入氨气。将溶液过滤后进行真空蒸发,直至大部分结晶由溶液中析出为止,再冷却、干燥,即得成品。2.硫化铵法 系将碘与硫化铵作用而得。直接法 在碘中加入氨水及过氧化氢水溶液,溶液经蒸发结晶而得。
