General description

Diisooctylphosphinic acid is an organophosphorous acid.

Application

Diisooctylphosphinic acid (DiOPA) may be used in the following studies:
  • As the surface passivating ligand in the synthesis of magic-sized CdSe and CdTe nanocrystals.
  • As extractant in the extraction of Indium(III) from sulfate solutions.
  • As ligand to investigate the solubility of four copper ligand systems in supercritical CO2.
  • As acid ligand for the Supercritical fluid extraction (SFE) of divalent metals (Zn2+, Cu2+, Pb2+, Cd2+ and Cr3+) from sand and fly ash using CO2.
