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 MgSO
4 and bayerite is used to prepare single-phase,MgAl
2O
4 spinel nanoparticles by calcining the powder mixture at 800
oC.
[8]MgSO
4 (anhydrous) can also be used as a drying agent in organic synthesis for the removal of traces of water from organic extracts.
