Abraham Model Correlations For Predicting Gas-To-Liquid Partition Coefficients And Activity Coefficients Of Organic Solutes Dissolved In 1-(2-Methoxyethyl)-1- Methylpyrrolidinium Tris(Pentafluoroethyl)Trifluorophosphate, Rui Jiang, Jared L.

Chromatographic retention factors were measured for 45 different organic solutes of varying polarity and hydrogen-bonding capability on an anhydrous 1-(2-methoxyethyl)-1-methylpyrrolidinium tris(pentafluoroethyl)trifluorophosphate, ([MeoeMPyrr]+ [FAP]– ), stationary phase at both 323 K and 353 K. The experimental retention factor data were combined with recently published thermodynamic data for solutes dissolved in ([MeoeMPyrr]+ [FAP]– ) to give the corresponding gas-to-liquid partition coefficients (log K). The water-to-anhydrous ([MeoeMPyrr]+ [FAP]– ) partition coefficients (log P) were also calculated using published gas-to-water partition coefficient data for the solutes studied. The derived partition coefficients were analyzed in accordance with the Abraham model. The Abraham model expressions that …
Determination Of The Solubilizing Character Of 1-Methoxyethyl-1- Methylpiperidinium Tris(Pentafluoroethyl)Trifluorophosphate Based On The Abraham Solvation Parameter Model, Pamela Twu, Jared L. Anderson, Timothy W. Stephens, William E. Acree Jr., Michael H. Abraham
Determination Of The Solubilizing Character Of 1-Methoxyethyl-1- Methylpiperidinium Tris(Pentafluoroethyl)Trifluorophosphate Based On The Abraham Solvation Parameter Model, Pamela Twu, Jared L. Anderson, Timothy W. Stephens, William E. Acree Jr., Michael H. Abraham

Chromatographic retention data were measured for a chemically diverse set of organic solutes on an anhydrous 1-methoxyethyl-1-methylpiperidinium tris(pentafluoroethyl)trifluorophosphate, ([MeoeMPip]+ [FAP]–), stationary phase at both 323 K and 353 K. The experimental retention factors were combined with previously published thermodynamic data and gas-to-water partition coefficient data to yield gas-to-anhydrous ionic liquid (IL) and water-to-anhydrous IL partition coefficients. The three sets of partition coefficient data were analyzed in accordance with the Abraham model. The Abraham model correlations that were determined in the present study describe the observed gas-to-([MeoeMPip]+[FAP]–) (log K) and water-to-([MeoeMPip]+[FAP]–) (log P) partition coefficient data to within average standard deviations …

Previously reported ion-specific equation coefficients for both the Abraham general solvation model and Goss modified Abraham model are updated using recently measured activity coefficient, gas chromatographic retention factor, and solubility data for solutes dissolved in room temperature ionic liquids (RTILs). Reported for the first time are equation coefficients for 1-propyl-2,3-dimethylimidazolium cation, and octylsulfate and thiocyanate anions. In total nine sets of cation-specific and eight sets of anion-specific equation coefficients have been determined for each model. The derived correlations describe the 976 experimental gas-to-RTIL partition coefficients to within a standard deviation of 0.12 log units and the 955 experimental water-to-RTIL partitions …
