General description
Magnesium perchlorate (Mg(ClO4)2) is widely used as drying agent for gases. It can remove water from gases (with no organic contaminants) at the rate of 0.001mgwater/l.
Application
干燥管的填充剂（尤其是用于元素分析）
Magnesium perchlorate (Mg(ClO4)2) may be employed as a catalyst in the following studies:
- Preparation of a-aminophosphonates.
- Enantioselective Diels-Alder reaction between cyclopentadiene and 3-acryloyl-1,3-oxazolin-2-one.
- Preparation of imines and phenylhydrazones.
- Protection of alcohols in the form of t-butyl ethers.
