Speeds of sound, densities, and viscosities of (cumene + ethanol or 1-propanol) at 298.15 and 308.15 K

Abstract

The speed of sound, density, and viscosity of { xC 6H 5CH(CH 3) 2 + (1 − x)C 2H 5OH} and { xC 6H 5CH(CH 3) 2 + (1 − x)C 3H 7OH} have been measured at 298.15 and 308.15 K for 0 < x < 1. From experimental results, the isentropic compressibility and its excess value along with the excess viscosity and excess molar Gibbs free energy for the activation of flow have been computed and are presented as functions of x. The parameter d of the Grunberg and Nissan expression has also been calculated. The deviations from additivity in the values of various parameters indicate interactions between unlike molecules.
