一般描述

高氯酸镁（Mg（ClO4）2）广泛用作气体干燥剂。它能以 0.001 mg 水/L 的速率从气体中去除水分（没有有机污染物）。

应用

高氯酸镁可用作合成下列化合物的催化剂：
  • α-氨基膦酸盐通过胺、醛或酮与二-/三烷基亚磷酸酯之间的三组分反应。
  • 由羰基化合物与胺和苯肼缩合形成亚胺和苯腙。
  • 通过 β-二酮和脂肪族或芳香醛之间发生 Knoevenagel 缩合，形成 Knoevenagel 加成物。
它也可用于催化醇类的保护，作为叔丁基醚。
高氯酸镁（Mg(ClO4)2）可用作以下研究中的催化剂：
  • 制备 α-氨基膦酸盐。
  • 环戊二烯与 3-丙烯酰基-1,3-恶唑啉-2-酮之间的对映选择性 Diels-Alder 反应。
  • 亚胺和苯腙的制备。
  • 以叔丁基醚的形式保护醇类。
