DENSITY, VISCOSITY, REFRACTIVE-INDEX, AND SPEED OF SOUND IN BINARY-MIXTURES OF 2-ETHOXYETHANOL WITH N-ALKANES (C-6 TO C-12), 2,2,4-TRIMETHYLPENTANE, AND CYCLOHEXANE IN THE TEMPERATURE INTERVAL 298.15-313.15 K

Experimental results of density, viscosity, refractive index, and spee d of sound in mixtures of 2-ethoxyethanol with n-alkanes (C-6 to C-12) , 2,2,4-trimethylpentane, and cyclohexane are presented over the entir e composition range at 298.15, 303.15, 308.15, and 313.15 K. These res ults are fitted simultaneously with mixture composition and temperatur e to an empirical equation. The computed values of excess molar volume and deviations in viscosity, molar refractivity, speed of sound, and isentropic compressibility are fitted to the Redlich-Kister polynomial equation to estimate the adjustable parameters and standard deviation s. The effect of the size and shape of the alkanes on excess quantitie s is discussed. Excess molar volumes and deviations in viscosities sho w a systematic increase with increasing temperature. However, the devi ations in molar refractivities are not dependent on temperature.
