摘要
The physical property data (densities, excess molar volumes, viscosities, surface tensions, and refractive indices) for ethanol + glycerol have been determined at 294 K and atmospheric pressure. Densities were determined by a vibrating-tube densitometer, viscosities were determined by U-tube viscometers, surface tensions were determined by the Du Nouy ring method, and refractive indices were determined by an Abbe refractometer. Excess molar volumes were computed from density values and were fit to the Redlich-Kister equation.
