Complex Formation between Dimethyl Methylphosphonate and Hexafluoroisopropanol
Abstract
A solvent/water partitioning method was used to measure the complex formation between dimethyl methylphosphonate (DMMP) and hexafluoroisopropanol (HFIP). The highest formation constant was obtained when n-hexane was used as the partitioning solvent. Other solvents all interfered to some extent with complex formation, probably by interacting with HFIP. The log formation constant in carbon tetrachloride was 3.46 + or - 0.10 at 21 C, which was similar to literature estimates for other phosphonates. The data support formation of H- bond charge transfer complexes as the mechanism for HFIP interaction with phosphonates and as primarily responsible for HFIP extraction of these compounds from water. Keywords: Complexation, Dimethyl methylphosphonate (DMMP), Hexafluoroisopropanol (HFIP).
