摘要：

The cation and anion functional group contribution Abraham model that was previously proposed for mathematically correlating the partitioning coefficients of organic solutes and gases into anhydrous ionic liquid solvents has been extended to enthalpies of solvation Numerical group values are determined for 10 cation functional groups and for 10 anion functional groups from regression analyses of 1077 experimental enthalpies of solvation The derived correlations describe the 1077 experimental values to within a standard deviation of about 1 74 kJ/mole (C) 2010 Elsevier B V All rights reserved
