Density, viscosity, refractive index, and speed of sound in binary mixtures of methyl acetate plus ethylene glycol or plus 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, V-E, deviations in viscosity, Delta eta, molar refractivity, Delta R, speed of sound, Delta u, and isentropic compressibility, Delta k(S), have been calculated. These quantities have been fitted to the Redlich-Kister type equation to derive the binary coefficients and standard errors.
