Binary mixture properties of diethyl ether with alcohols and alkanes from 288.15 K to 298.15 K

Density, refractive index and speed of sound of the binary mixtures (diethyl ether+methanol, or ethanol, or n-hexane, or n-heptane) from 288.15 K to 298.15 K and atmospheric pressure, have been measured over the whole composition range. Excess molar volumes, changes of refractive index on mixing and excess isentropic compressibilities for the binary systems were calculated and fitted to Redlich–Kisterʹs equation to estimate the fitting parameters and the root mean square deviations between calculated and experimental data. Values of density and refractive index were evaluated and compared by different methods. Excess partial molar volumes and those corresponding to the infinite dilution condition are also calculated.
