Description

General description

Copper(II) nitrate hemi(pentahydrate) is an inorganic copper salt.

Application

Catalyzes oxidative coupling of 2,6-dimethylphenol to produce a polymer which is an important engineering material.

Copper(II) nitrate hemi(pentahydrate) may be used in the following stuies:

• Preparation of water/sodium bis(2-ethylhexyl)sulfosuccinate/n-heptane microemulsions (consisting of aqueous core of the reversed micelles some water-soluble salts [CaCl₂, Na₂HPO₄, Cu(NO₃)₂]).
• As a copper precursor for the preparation of thin films of Cu₂ZnSnS₄ (CZTS).
• Preparation of 4-methoxypyridine-(pyridine-2,6-dicarboxylato-N,O,O′) copper (II).
• Mechanochemical synthesis of coordination pillared-layer frameworks (CPLs), particularly CPL-1.

Copper(II) nitrate hemi(pentahydrate) may be used in the preparation of novel coordination polymers.
