We performed simulations for several concentrations of methanol and densities of mixtures. Similar to that observed for ambient conditions, the 600 K solution containing 0.12 mole fraction of methanol at the density of 0.98 gm.cm-3yields the highest CV. The intermolecular structure between water and methanol molecules at this concentration was also found to be enhanced. Hydrophobic hydration, relative to ambient conditions, is diminished slightly at the concentration of Cvmaximum and diminishes drastically for the other concentrations. © 2001 Elsevier Science Inc.Mahidol UniversityChemistryComputer ScienceMaterials ScienceConference PaperSCOPUS10.1016/S1093-3263(00)00100-5
