摘要：

Dynamic viscosity and speed of sound of the ternary mixture (methyl acetate + methanol + ethanol) at 298.15 K and atmospheric pressure have been measured over the whole range of mixture compositions. Viscosity deviations and deviation in isentropic compressibility for the ternary system were calculated and fitted to Cibulka's equation to estimate the fitting parameters and the root-mean-square deviations between calculated and experimental data. To correlate viscosities of the ternary system from binary data, different equations have been used and theirs parameters are shown. To predict the viscosity of the ternary mixture, several methods have been proposed; some of them are based on contribution groups, and the other ones use the binary correlation parameters. Some methods that predict viscosity deviations by means of binary contributions have been applied, and their root-mean-square deviations are presented.
