| Outline of Final Research Achievements |
Water-alcohol mixtures at high temperature and pressure are expected as a new reaction solvent. In this study, density and viscosity data, which are required for process development and design, were measured at high temperatures and pressures. The density and viscosity measurement system developed by our group were improved, and those of water-methanol, water-ethanol and water-n-propanol were measured with high accuracy at temperatures under 618 K and pressures under 40 MPa. Molecular dynamics simulation reflecting measured density data were performed and the relationship between macroscopic and microscopic properties were clarified. Moreover, densities and viscosities measured in this study and reported in the literature were correlated continuously up to high temperatures and high pressures using the combination of the Eyring's theory, equation of state and mixing rule.
