Cobalt(II) stearate is a metal-organic compound, a salt of cobalt and stearic acid with the chemical formula C36H70CoO4.[2][3] The compound is classified as a metallic soap, i.e. a metal derivative of a fatty acid.[4]
Synthesis
An exchange reaction of sodium stearate and cobalt dichloride:
- [math]\displaystyle{ \mathsf{ CoCl_2 + 2C_{17}H_{35}COONa \ \xrightarrow{}\ Co(C_{17}H_{35}COO)_2\downarrow + 2NaCl } }[/math]
Physical properties
Cobalt(II) stearate forms a violet substance, occurring in several crystal structures.
Insoluble in water.[citation needed]
Uses
Cobalt(II) stearate is a high-performance bonding agent for rubber. The compound is suitable for applications in natural rubber, cisdene, styrene-butadiene rubber, and their compounds to bond easily with brass- or zinc-plated steel cord or metal plates as well as various bare steel, especially for bonding with brass plating of various thicknesses.[5]
