Abstract

Enthalpies of dilution of solutions of urea (U) in formamide (FA) and ethylene glycol (EG), and solutions of tetramethylurea (TMU) in FA, are measured at 298.15 K to study displays of solvophilic and solvophobic effects in solvents with a spatial hydrogen-bond network. Homotactic enthalpic coefficients of pair (h22) and triple (h222) interactions between solvated molecules of the solute (U or TMU) are calculated from the calorimetric results. Calculated values are compared to literature data for U and TMU solutions in water (H2O) and TMU solutions in EG. It is established that unlike the effects of 2–2 interaction in (EG + U) and (H2O + U) systems, the h22 parameter for U in FA has a positive sign and is quite low in absolute value (~160 J kg mol−2). It is therefore concluded that there is complementarity in Н-bond-associated structures of the solvent (in bulk) and the U–FA solvatocomplex formed in it. The character of distribution of the h22 values for TMU in the FA (~587) < EG (~649) \( \ll \) H2O (~2346 J kg mol−2) series of solvating media is evidence of the considerably greater role of solvophobic effects in aqueous solution.
