Copper(II) stearate is a metal-organic compound, a salt of copper and stearic acid with the formula Cu(C17H35COO)2.[2][3] The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid.
Synthesis
[edit]Exchange reaction of sodium stearate and copper sulfate:[4][5]
Physical properties
[edit]Copper(II) stearate forms a blue-green amorphous substance[6] similar to plasticine both in appearance and touch.
Insoluble in water, ethanol, or ether; soluble in pyridine.[7]
Chemical properties
[edit]The compound is stable and non-reactive under normal conditions.[8]
When trying to ignite, copper stearate first melts and then begins to burn with a green (at the base) flame, then it quickly turns black due to the formation of cupric oxide:
Uses
[edit]The compound is used in the production of antifouling paint and varnish materials.
Also used as a component in casting bronze sculptures.[9]
Also applies as a catalyst for the decomposition of hydroperoxides.[10]
