Density, Viscosity, Refractive Index, and Speed of Sound in Binary Mixtures of Methyl Acetate + Ethylene Glycol or + Poly(ethylene glycol) in the Temperature Interval (298.15−308.15) K

Experimental results of density, viscosity, and refractive index at 298.15, 303.15, and 308.15 K and speed of sound at 298.15 K in the binary mixtures of methyl acetate + ethylene glycol or + poly(ethylene glycol) are presented over the whole range of mixture composition. From these data, excess molar volume, VE, deviations in viscosity, Δη, molar refractivity, ΔR, speed of sound, Δu, and isentropic compressibility, ΔkS, have been calculated. These quantities have been fitted to the Redlich−Kister type equation to derive the binary coefficients and standard errors.
