General description

Copper (II) acetate monohydrate is soluble in water and slightly soluble in methanol, diethylether and acetone. It can be synthesized by reacting acetic acid with copper (II) carbonate or copper(II) hydroxide or copper (II) oxide. Large scale commercial production is undertaken by placing copper metal in the presence of air and refluxing acetic acid. As a transition metal acetate, it can be used to form oxide nanoparticles by sonochemical methods.

Application

Used in the synthesis of copper oxide nanoparticles, Cu2ZnSnS4 films, which find applications in solar cells. It may be used in Zinc Oxide varistors, as a catalyst in the polymerization of organic materials and as a mordant in the dying of textiles. Industrially, it may be used as a ceramic pigment and as a fungicide.
