Cobalt oleate is an organometallic compound with the formula Co(C18H33O2)2. When cobalt oleate is added to non-polar solvents, the viscosity rapidly increases, and then continues increasing over time. This unusual viscosity effect is caused by the formation of a weak coordination complex with the solvent molecules.[1]
Preparation
[edit]Cobalt oleate can be synthesized by heating a solution of sodium oleate and cobalt(II) chloride to 70 °C.[2]
- 2 NaC18H33O2 + CoCl2 → 2 NaCl + Co(C18H33O2)2
