CYANEX® 272 is a dialkyl phosphinic acid extractant widely used for the separation of cobalt from nickel to produce high purity cobalt salts and cobalt metal. Since the active component of CYANEX 272 extractant is a phosphinic acid, metals are extracted through a cation exchange mechanism. Although CYANEX 272 extractant is selective for cobalt in the presence of nickel, a variety of other cations can also be extracted depending on the solution pH. CYANEX 272 extractant is totally miscible with common aromatic and aliphatic diluents, and is extremely stable to both heat and hydrolysis.
