Applications
UsesCopper(II) acetate is used as a pigment for ceramics; in the manufacture of Paris green; in textile dyeing; as a fungicide; and as a catalyst.
DescriptionCopper (II) acetate, also referred to as cupric acetate, is the chemical compound with the formula Cu(OAc)22 where OAc- is acetate (CH3CO2-). The hydrated derivative, which contains one molecule of water for each Cu atom, is available commercially. Anhydrous Cu(OAc)2 is a dark green crystalline solid, whereas Cu2(OAc)4(H2O)2 is more bluish-green. Since ancient times, copper acetates of some form have been used as fungicides and green pigments. Today, copper acetates are used as reagents for the synthesis of various inorganic and organic compounds. Copper acetate, like all copper compounds, emits a blue-green glow in a flame.
HistoryCopper (II) acetate was historically prepared in vineyards, since acetic acid is a byproduct of fermentation. Copper sheets were alternately layered with fermented grape skins and dregs left over from wine production and exposed to air. This would leave a blue substance on the outside of the sheet. This was then scraped off and dissolved in water. The resulting solid was used as a pigment, or combined with arsenic trioxide to form copper acetoarsenite, a powerful insecticide and fungicide called Paris Green or Schweinfurt Green. During the Second World War copper acetate was used as shark repellent . Under war conditions, before adoption it has been tested only very briefly (while in general successfully). The source says copper acetate does repel sharks in some situations but not in all.
UsesCopper(II) acetate is used in biochemical applications such as DNA extraction. It is used as a source of copper in inorganic synthesis, an oxidizing agent and catalyst in organic synthesis. It is also used to couple two terminal alkynes to make a 1,3-diyne. It is widely used in pigments, manufacture of paris green, textile dyeing, skin conditioner in cosmetics, antioxidant and stabilizer in food grade polymers.
UsesUsed as a catalyst or oxidizing agent in organic syntheses
