General description

Cobalt(II) chloride hexahydrate is a hydrated form of cobalt chloride. It is used as a catalyst for various organic reactions such as acetylation and tosylation of alcohols, chemoselective reduction of carboxylic esters, and condensation reactions.

Application

Cobalt(II) chloride hexahydrate can be used as a catalyst:      
  • To convert various aldoximes into corresponding nitriles in the presence of an inorganic base.      
  • To prepare organic-inorganic polyvinylidene fluoride nanofiber composites (PVDF/CoCl2) for the production of pure hydrogen production from NaBH4.

It can also be used as a cobalt precursor to synthesize nickel-cobalt-based binary metal phosphide (NiCoP) hollow spheres, which are used for electrocatalysis and energy storage (supercapacitor) applications.

Abnormal wear of cobalt-containing metal-on-metal joints is associated with inflammatory pseudotumours. Cobalt ions activate human toll-like receptor 4 (TLR4), which normally responds to bacterial lipopolysaccharide (LPS) in sepsis. Activation of TLR4 by LPS increases the expression of chemokines IL-8 and
