Ultrasonic Study of Excess thermoacoustic Parameters in Binary Mixtures of Propylene Glycol and Hexanol
نویسندگان
چکیده
Excess thermo acoustical parameters such as excess intermolecular free length (Lf), excess adiabatic compressibility (), excess free volume (Vf), excess enthalpy (H) have been measured for propylene glycol in Hexanol for various mole fractions at 303K temperature through ultrasonic sudy. 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. The final results obtained have indicated that intermolecular hydrogen bond formation is stronger for (0.8Pg+0.2hex) molar ratio of the binary mixture liquid complex compare to that of other systems and hence this mixture is strongly recommended in therapeutical drugs, pharmaceutical industry and for the high heat transferability when needed

In this study, the densities, excess molar volumes and partial molar volumes of four binary systems containing N,N-dimethyl acetamide (DMAc) with 1-alkanols (1-butanol up to 1-heptanol) are measured at 298.15 K. The results showed both constructive and expansive excess volumetric behavior for studying binary mixtures. Deviation values of heavy alcohol have more positive and less negative excess...
