摘要: ABSTRACTPartition coefficient and gas solubility data have been assembled from the published chemical engineering literature for solutes dissolved in anhydrous 1-butyl-3-methylimidazolium dicyanamide, 1-butyl-2,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide, 4-cyano-1-butylpyrridinium bis(trifluoromethylsulfonyl)imide. More than 60 experimental points were gathered each IL solvent. The compiled used to derive Abraham model correlations describing solute transfer properties into three solvents both phase water. derived mathematical described observed properties, expressed as logarithm of water-to-IL partition gas-to-IL solvent coefficient, within standard deviations 0.125 log units (or less). ion-specific equation coefficients are also calculated 4-cyano-1-butylpyridi...
