Linear free energy relationship correlations for room temperature ionic liquids / Laura M. Sprunger in Industrial & engineering chemistry research, Vol. 48 N° 8 (Avril 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 8 (Avril 2009) . - pp. 4145–4154 Titre : Linear free energy relationship correlations for room temperature ionic liquids : revised cation-specific and anion-specific equation coefficients for predictive applications covering a much larger area of chemical space Type de document : texte imprimé Auteurs : Laura M. Sprunger, Auteur ; Jennifer Gibbs, Auteur ; Amy Proctor, Auteur Année de publication : 2009 Article en page(s) : pp. 4145–4154 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Ion-specific  equation  coefficients  RTIL  partition  Abraham  model Résumé : 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 to within a standard deviation of 0.15 log units.
