说明

七水硫酸镁是镁的水合盐。它通常用作有机合成中的催化剂。

一般描述

Magnesium sulfate heptahydrate is a hydrated salt of magnesium. It is commonly used as a catalyst in organic synthesis.
 

应用

Magnesium sulfate heptahydrate can be used as a Lewis acid catalyst to synthesize:      
  • Phenazine and quinoxaline derivatives via a condensation reaction between o-phenylenediamines and 1,2-dicarbonyl compounds.
  • Imidazole derivatives via one-pot multicomponent condensation reaction of aromatic aldehydes, benzil, aliphatic, and aromatic primary amines.
NaBH4 supported on MgSO4 7H2O can be used as an efficient catalyst for the reduction of α, β-unsaturated carbonyl compounds to corresponding alcohols.
