说明

一般描述

硫酸镁是具有保胎能力的镁盐。[1]它的功能是在手术中和手术后引起镇痛效果。[2]它被报道能够预防子痫。[3]它通过盐析相,从水溶性溶剂中去除水。[4]
 

应用

硫酸镁可用作有机提取的干性试剂。[5]
Magnesium sulfate (anhydrous) can be used as a catalyst:      
  • In Biginelli reactions to synthesize dihydropyrimidinones by solvent-free conditions.[6]      
  • In the synthesis of 2-imidazolines by the reaction of aldehydes and ethylenediamine in the presence of hydrogen peroxide and sodium iodide.[7]
The mixture of MgSO4 and bayerite is used to prepare single-phase,MgAl2O4 spinel nanoparticles by calcining the powder mixture at 800 oC.[8]
MgSO4 (anhydrous) can also be used as a drying agent in organic synthesis for the removal of traces of water from organic extracts.
