高氯酸镁制备

1.将水合物高氯酸镁加热蒸发至凝固（约145ºC），快速搅拌下并继续加热至170-200ºC（不得超过230ºC），所得熔融盐保温2-h，冷却后粉碎，于13.33Pa下于170ºC干燥2-3h，再升温至220-240ºC干燥3h，即得无水高氯酸镁。

2.将高氯酸镁的结晶水合物在瓷皿中于电热板上加热制取。加热至145～147℃时，熔于自身的结晶水中。随水分蒸发，液体凝固为多孔状物质（三水合物）。因此时应强烈搅拌，然后升温至170～200℃（不得超过230℃），将熔盐在此温度下保存1～2h。冷却后，粉碎成直径3～4mm的小块，放入圆底烧瓶中，与真空泵相连（中间装有CaCl2干燥塔）。在133Pa压力下加热到170℃约2～3h，再升温至220～240℃加热3h。产品应储存于密闭瓶中。

3.制法将化学纯氧化镁加到含量为30%的化学纯高氯酸中，使其饱和，滤出未溶的氧化镁，搅拌滤液，加入高氯酸至刚果红呈弱酸性反应：

然后加热反应液至出现结晶薄膜，冷却结晶，过滤所得结晶，用热水溶解，滤去不溶物后，再蒸发浓缩至出现结晶薄，冷却结晶，所得结晶甩干，即为水合高氯酸镁。母液重新蒸发浓缩、结晶，还可获得成品。
