Densities, Viscosities, and Surface and Interfacial Tensions of the Ternary Mixture Water + Ethyl Butyrate + Methanol at 303.15 K

摘要

The excess molar volumes, VE, viscosity deviations, Δη, and excess surface tensions were calculated from the measured density, viscosity, and surface tension values, σ, over the whole miscibility composition range for the ternary system water + ethyl butyrate + methanol and their constituent binaries, at 303.15 K and atmospheric pressure. The liquid interfacial tension was measured in the liquid−liquid equilibrium range at the same conditions of temperature and pressure. A Redlich−Kister type equation was used to correlate binary and ternary VE and Δη data. For the correlation of the surface tension of binary and ternary data, the Santos et al. equation was used. The interfacial tension was correlated with the Li and Fu equation.
