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.
• To compose the electrolyte for the electrodeposition of Cu-Zn-Sn precursors, required for the preparation of Cu2ZnSnS4 (CZTS) thin films.
• As catalyst for the dehydration of alcohols.
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). CuSO4·5H2O along with metallic copper was employed as a catalyst for the synthesis of different ligand-arm functionalized azoamides. On heating above 560°C, it decomposes to CuO.
