| Bis(2,4,4-trimethylpentyl)phosphinic acid (diisooctylphosphinic acid) is a slightly water soluble compound which has a variety of applications based upon its metal ion chelating properties. Fe(III) and In(III) ions, for example, can be ligated by phosphinic acids allowing them to transfer from an aqueous into an organic phase, treatment of the organic soluble metal complexes with aqueous acid or base as appropriate selectively strips the phosphinic acid ligands and the metal ions re-enter the aqueous phase. Similarly, heavy metal contaminants can be removed from solid materials using diisooctylphosphinic acid as a ligand in super critical fluid extraction (SFE) processes. Bis(2,4,4-trimethylpentyl)phosphinic acid can also be used as an additive to create halogen-free flame retardant adhesives.
