Application

Copper(II) sulfate pentahydrate may be employed in the following studies:
  • As a catalyst for the acetylation of alcohols and phenols under solvent-free conditions.[1]
  • To compose the electrolyte for the electrodeposition of Cu-Zn-Sn precursors, required for the preparation of Cu2ZnSnS4 (CZTS) thin films.[2]
  • As catalyst for the dehydration of alcohols.[3]

General description

Copper(II) sulfate pentahydrate (CuSO4·5H2O, Blue vitriol) is a hydrated copper(II) salt. It undergoes hydrothermal reactions with the tripodal ligands to afford metal-organic frameworks (MOFs).[4] CuSO4·5H2O along with metallic copper was employed as a catalyst for the synthesis of different ligand-arm functionalized azoamides.[5] On heating above 560°C, it decomposes to CuO.[3]
