| 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. |
