Excess Molar Volumes,Viscosity Deviations and Isentropic Compressibility of Binary Mixtures Containing 1,3-Dioxolane and Monoalcohols at 303.15 K

摘要

The excess molar volume (V~E),viscosity deviations (DELTA_(eta)) and Gibbs excess energy of activation for viscous flow (G~(*E)) have been investigated from density (rho) and viscosity (eta)) measurements of eight binary mixtures of 1,3-dioxolane with methanol,ethanol,1 -propanol,2-propanol,1-butanol,2-butanol,t-butanol,and i-amyl alcohol over the entire range of mole fractions at 303.15 K.The viscosity data have been correlated with the Grunberg and Nissan equation.Furthermore,excess isentropic compressibilities (K_S~E) have been calculated from ultrasonic speed measurements of these binary mixtures at 303.15 K.The deviations have been fitted by a Redlich-Kister equation and the results are discussed in terms of molecular interactions and structural effects.The excess properties are found to be either negative or positive depending on the molecular interactions and the nature of the liquid mixtures.The systems studied exhibit very strong cross association through hydrogen bonding.
