Ultrasonic, Density and Viscosity Studies in Binary Mixtures of Propylene Glycol and 1-Pentanol at Room Temperature

Abstract

Speed of sound (U), Density (), and viscosity () values for the binary mixture systems of Propylene Glycol with 1-pentanol including those of pure liquids were measured over the entire mole fraction range at temperature 303.15 K. From the experimentally determined values, thermo-acoustic parameters such as excess isentropic compressibility (Ks E), excess molar volume (V E) and excess free length (Lf E) and excess enthalpy (H E) have been calculated. These results have been explained on the basis of intermolecular interactions between the components in the liquid mixture and correlations among the parameters are discussed.

Thermophysical Studies of Binary Liquid Mixture of 1-Pentanol and Cyclopentyl methyl ether at Temperature 293.15K

“…Here Table 1 reveals the literature and experimental values of 1-Pentanol and Cyclopentyl methyl ether at the temperature 293.15K [17][18][19] . The Excess molar volume (V E ) values are positive and excess viscosity(η E ) values are negative in system.…”
