Abraham solvation parameter model: calculation of ion-specific equation coefficients for the N-Ethyl-N-methylmorpholinium and N-Octyl-N-methylmorpholinium cations

Abstract

ABSTRACT Abraham model correlations are derived for describing gas-to-ionic liquid and water-to-ionic liquid partition coefficients from published experimental data for solutes dissolved in both N-ethyl-N-methylmorpholinium bis(trifluoromethylsulfonyl)imide and N-octyl-N-methylmorpholinium bis(trifluoromethylsulfonyl)imide. Derived Abraham model correlations describe the observed partition coefficient data to within 0.14 log units. As part of the current study, we also determined Abraham model ion-specific equation coefficients for both N-ethyl-N-methylmorpholinium and N-octyl-N-methylmorpholinium cations.
