	abstract = {The classical concept of "iceberg formation" is modified by our recent thermodynamic studies. The local enhancement of the hydrogen-bond network of H2O in the immediate vicinity of small nonelectrolyte solutes (i.e., the "iceberg formation") is still correct. However, the hydrogen-bond probability of bulk H2O away from solutes is reduced progressively, as the solute composition increases. When the hydrogen-bond probability of bulk H2O is reduced to the bond percolation threshold of the hexagonal ice connectivity, the hydrogen-bond percolation is lost and a qualitatively different mixing scheme sets in, whereby the solution consists of two kinds of clusters. In the solute-rich region, solute molecules form Clusters of its own kind. Thus, the "iceberg, formation" is basically correct within a narrow range in the H2O-rich region for small nonelectrolyte solutes. Thus, reference made to the "iceberg" concept in recent literatures should be clarified in terms of the concentration range and the size of solute in question.},

Partial pressures and hence, the excess chemical potentials of iBE were calculated by the Boissonnas method. Excess partial molar enthalpies were measured, and the excess partial molar entropies of iBE were then calculated at 20degreesC. These data and their mole fraction dependence indicated that there are three mixing schemes operative, in the same way as in aqueous 2-n-butoxyethanol (nBE) studied extensively by us. The details of each mixing schemes are identical, but the locus of the transition between mixing schemes I and II occurs at a smaller mole fraction than for aqueous nBE. This suggests that iBE is a stronger hydrophobic solute than nBE, which is consistent with the common understanding. (C) 2002 Elsevier Science B.V. All rights reserved.},

Using alcohol excess partial molar enthalpies, H-AL(E), determined earlier in this laboratory (Can. J. Chem. 74, 713 (1996)), we have calculated excess partial molar entropies for the alcohols, S-AL(E), where AL stands for an alcohol. We then calculated, numerically, the entropic interaction, S-AL-AL(E) = N(partial derivativeS(AL)(E)/partial derivativen(AL))(p,T,nW), where n(AL) is the amount of AL, n(W) is the amount of H2O, and N is the total amount of solution. S-AL-AL(E) signifies the effect of addition of AL upon the entropic situation of existing AL in solution. Using these quantities, the mixing schemes in aqueous alcohols have been studied. The earlier conclusions, which used H-AL(E) and H-AL-AL(E) alone, are confirmed. Furthermore, the order of the relative hydrophobic nature of alcohols is established from the behaviour of S-AL-AL(E) and of H-AL-AL(E) as methanol < ethanol < 2-propanol < 1-propanol.},

The latter three response functions were used to calculate the mean-square fluctuation densities, which signifies the amplitude, or the intensity, of fluctuations in volume, entropy or cross (entropy-volume) fluctuations. Furthermore, we calculated the (mean-square) normalized fluctuations that are indicative of the wavelength, or the extensity, as well as the amplitude of respective fluctuations. The behaviour of these thermodynamic quantities were compared with those obtained earlier in this laboratory for aqueous methanol, ethanol, propan-1-ol, tert-butanol (tert-butyl alcohol), and 2-butoxyethanol. We conclude that in the water-rich region of aqueous butan-1-ol, mixing scheme I is operative as in other alcohols, whereby butan-1-ol molecules enhance the hydrogen bond network of H2O in their immediate vicinities with concomitant reduction of hydrogen bond probability in the bulk H2O away from solutes. However, before reaching the phase separation boundary there was no signature indicative of the transition of mixing scheme observed in other aqueous alcohols. Thus, in aqueous butan-1-ol phase separation occurs directly from mixing scheme I, without going through mixing scheme II, which we argued earlier to be a preparation stage for phase separation for the other alcohols.},

The response function data by the same group were also used to evaluate amplitude and wavelength of mean-square fluctuations in terms of volume, entropy, and cross between volume and entropy. All the above quantities and their dependence on the mol fraction of solute, i.e., the effect of additional solute on the above quantities were used to study the effect of acetonitrile on the molecular organization of H2O. It was found that acetonitrile works as a stronger structure-making solute than methanol. Rather its effect on H2O is about the same as that of propan-1-ol.},

Based on the knowledge accumulated in our laboratory on the binary aqueous l-propanol, the effect of NaCl on H2O became apparent.

	abstract = {Excess partial molar enthalpies were measured in ternary aqueous solutions, tert-butyl alcohol (TBA)DMSO-H2O, and lysozyme (L)-alcohols (A)-H2O. The solute-solute interactions were evaluated as the derivatives of these data with respect to the mole fraction of a solute. In the water-rich region, where the so-called mixing scheme I is operating in binary aqueous solutions of TEA, DMSO or alcohols, two solutes in TBA-DMSO-H2O seem to modify the hydrogen bond network of H2O in an additive manner. Here, mixing scheme I refers to the way in which a solute (hydrophobic) modifies the molecular organization of H2O. Specifically, a solute enhances the hydrogen bond strength of H2O in its immediate vicinity. On the other hand, the probability of hydrogen bond in the bulk away from a solute is reduced, and it is still high enough, however, to keep the hydrogen bond network connected throughout the entire macroscopic: system. As the composition of solute increases, the hydrogen bond probability in the bulk decreases to the point at which the macroscopic bond connectivity is no longer possible. At this point, a new mixing scheme, II, sets in. For L-A-H2O mixtures at infinite dilution of L, the L-A interaction changes drastically from repulsive: to attractive at the boundary between I and II for binary aqueous alcohols. Moreover, a denatured lysozyme interacts with alcohols more strongly than the native form, and is more repulsive in mixing scheme I and more attractive in IT. This behaviour is shown to be consistent with the alcohol-dependent enthalpy of denaturation of lysozyme found by Velicelebi and Sturtevant [Velicelebi and Sturtevant, Biochem. 18 (1979) 1188-86].

The results for the water-rich region indicated that the presence of DMSO enhances the hydrogen bond network of H2O.

This was a result of the fact that the repulsion among solutes in terms of enthalpy surpassed the attraction in terms of entropy.

	abstract = {Excess partial molar volumes of 2-butanone V(m)E(B) and thermal expansivities alpha(p) were measured in the water-rich region of aqueous 2-butanone. The composition derivatives of both quantities showed anomalies at about X(B) = 0.033 (x(B) is the mole fraction of B). (partial derivative V(m)E(B)/partial derivative n(B))p,T,nW showed a step anomaly, while (partial derivative alpha(p)/partial derivatives n(B))p,T,nw exhibited a peak anomaly. The compositions at which these anomalies occurred match those of the step anomalies observed earlier in (partial derivative H(m)E(B)/partial derivative n(B))p,T,nW and (partial derivative S(m)E(B)/partial derivative n(B))p,T,nW in aqueous 2-butanone. These results are discussed in comparison with those obtained previously for aqueous 2-butoxyethanol.},

	abstract = {The excess partial molar enthalpies, H(m)E(i), in 2-butanone (BUT)-H2O mixtures were measured at 4.20, 20.00, and 25.00-degrees-C (i = BUT or H2O). The vapor pressures were also measured by a static method at 20.00 and 25.00-degrees-C. From the latter data, the partial pressures and hence the excess partial molar Gibbs free energies, G(m)E(i), were calculated by the method. The excess partial molar entropies, S(m)E(i), were then calculated at 20.00 and 25.00-degrees-C. From the composition derivatives of these partial molar quantities, the nature of the solute-solute interactions was discussed in relation to the global information about the mixture: existence of phase separation, the way in which the phase boundary slants, and existence of azeotropy and addition compound.},

	abstract = {The excess partial molar enthalpies of isobutyric acid (IBA), H(m)E(IBA), and those of H2O, H(m)E(H2O), were measured in aqueous solutions of IBA. The temperature dependence of H(m)E(IBA) at the infinite dilution suggested that the structure enhancement of the solvent H2O by IBA is weaker than those by tert-butanol (TBA) or 2-butoxyethanol (BE). The concentration dependence of H(m)E(IBA), and that of the enthalpic IBA-IBA interaction, N{partial H(m)E(IBA)/partial n(B)}, shows that there are two distinct mixing schemes bounded at about x(B) = 0.03, before reaching the two phase separation. Namely, the IBA-IBA interaction is repulsive below this boundary, while above this boundary it becomes attractive leading eventually to phase separation at a higher concentration. The transition between the two schemes is associated with a peak(negative) anomally in the fourth derivative of the free energy, N2 {partial H-2(m)E(IBA)/partial n(B)2}.},
