설명

일반 설명

Copper(II) sulfate acts as a redox catalyst along with potassium permanganate for the oxidation of alcohols. On heating above 560°C, it decomposes to CuO.5
It can find applications in agriculture as a nutrient for plants.[1] It can also serve as a precursor in the production of foliar bactericides and fungicides.[1]

애플리케이션

Copper(II) sulfate may be employed for the following studies:

• As a catalyst for the acetylation of alcohols and phenols under solvent-free conditions.[2]
• To compose the electrolyte for the electrodeposition of Cu-Zn-Sn precursors, required for the preparation of Cu₂ZnSnS₄ (CZTS) thin films.[3]
• As a Lewis acid catalyst for the dehydration of alcohols.5
