일반 설명
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.
애플리케이션
Magnesium perchlorate (Mg(ClO4)2) may be employed as a catalyst in the following studies:
- Preparation of α-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.
Magnesium perchlorate may be used as a catalyst in the synthesis of the following compounds:
- α-Aminophosphonates via three-component reaction between an amine, an aldehyde or a ketone and a di-/trialkyl phosphite.
- Imines and phenylhydrazones by the condensation of carbonyl compounds with amines and phenylhydrazine.
- Knoevenagel adducts via Knoevenagel condensation between β-diketones and aliphatic or aromatic aldehydes.

The mechanism of the gamma-radiolysis of the nucleotide guanosine-5'-monophosphate (5'-GMP) in the presence of Mg++ ions and cis-platinum was investigated. From high performance liquid chromatography and spectroscopy studies it was found that the OH radicals, produced in irradiated aqueous solutions
