Abraham model correlations for solute transfer into benzyl alcohol from both water and the gas phase
《Physics and Chemistry of Liquids》2012,50(1):116-126
ABSTRACTExperimental solubilities have been determined for anthracene, benzil, 2-chloroanthraquinone, 9-fluorenone, 2-hydroxybenzoic acid, 2-methoxybenzoic acid, 2-methylbenzoic acid, 3-methylbenzoic acid, phenothiazine, pyrene, and thioxanthen-9-one dissolved in benzyl alcohol at 298.15 K. The measured solubility data, combined with previously published activity coefficient and solubility data, are used to determine Abraham model correlations for solute transfer to benzyl alcohol from both water and from the gas phase. The derived Abraham model correlations were found to back-calculate the experimental partition coefficients and solubility ratios to within 0.14 log units (or less). 相似文献

Experimental solubilities were measured for 20 crystalline organic solutes dissolved in propanenitrile and for 13 crystalline organic solutes dissolved in butanenitrile at 298.15 K. Infinite dilution activity coefficient data for solutes dissolved in propanenitrile and butanenitrile have been compiled from the published chemical and engineering literature and converted into gas-to-liquid partition coefficients and water-to-organic solvent partition coefficients through standard thermodynamic relationships. Abraham model correlations were developed for describing solute transfer into both propanenitrile and butanenitrile by combining our measured solubility data with the partition coefficients that we calculated from the published activity coefficient data. The derived Abraham model correlations were found to back-calculate the observed partition coefficients and molar solubility data to within 0.14 log units. 相似文献

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