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.

CYANEX® 272 extractant also enables the recovery of various metals, such as cobalt from spent lithium-ion batteries, including those powering electric vehicles, e-bikes, power tools, electronics and stationary storage stations.
