Abraham model expressions for describing water-to-organic solvent and gas-to-organic solvent partition coefficients for solute transfer into anhydrous poly(ethylene glycol) dialkyl ether solvents at 298.15 K

ABSTRACT

Henry’s law constants and infinite dilution activity coefficients were compiled from the published chemical and engineering literature for gaseous solutes and organic liquids in butyl diglyme, butyl triglyme and tetraglyme. The published literature values were converted into water-to-liquid and gas-to-liquid partition coefficients using standard thermodynamic relationships. The calculated partition coefficients were correlated mathematically with the Abraham solvation parameter model. The derived Abraham model correlations can be used to predict the partitioning behaviour of additional solutes into dry, anhydrous butyl diglyme, butyl triglyme and tetraglyme.
