“…A large number of works have been devoted to the influence of solvent properties on the enthalpy of solvation. − Various scales of empirical parameters of solvents have been proposed for these purposes . The dependence of solvation enthalpies on empirical parameters of solvation ability such as dipolarity–polarizability and , basicity , of solvents was considered.…”

“…The dependence of solvation enthalpies on empirical parameters of solvation ability such as dipolarity–polarizability and , basicity , of solvents was considered. In a series of works, , multiparameter empirical correlations of solvation enthalpies with a complex of solvent parameters based on the Abraham equation are considered. The influence of molecular parameters and the physical properties of solvents on the solvation enthalpy was studied in works , based on the multiparameter equation from the scaled particle theory.…”

The enthalpies of dissolution, Δ sol H m ∞ , and solvation, Δ solv H m ∞ , of ether oligomers CH 3 O(CH 2 CH 2 O) n CH 3 (n = 1−4) in ethyl acetate, pyridine, N,Ndimethylformamide, and acetonitrile have been determined from calorimetric measurements at 298.15 K. The values of group contributions of repeated ether units and monoether fragment have been compared on the basis of the additive method.The contributions of ether group to Δ solv H m ∞ for oligomeric and monomeric molecules coincide within their uncertainties for solutions in highly polar solvents, in contrast to non-polar, moderately polar, and H-bonding solvents. The dependence of ether group contributions to Δ solv H m ∞ on the electron pair acceptance index of solvents E T N has been considered.
