Previously reported ion-specific equation coefficients for the Abraham general solvation model
are updated using recently published enthalpy of solution data for organic solutes dissolved in
room temperature ionic liquids (RTILs). Reported for the first time are equation coefficients for
1-hexyloxymethyl-3-methylimidazolium, 1,3-dihexyloxymethylimidazolium, 3-methyl-N-
butylpyridinium, tris(pentafluoroethyl)trifluorophosphate, and tetracyanoborate ions. In total 12
sets of cation-specific and 10 sets of anion-specific equation coefficients have been determined
for each model. The derived correlations describe the 942 experimental enthalpies of solvation
to within a standard deviation of about 1.65 kJ/mole.
Here’s what’s next.
