Study of Intermolecular Interaction in Dimethylsulphoxide + 1-Alkanols (1-Butanol, 1-Hexanol, 1-Octanol) At 303.15 K

Ultrasonic velocities, isentropic compressibilities and excess molar volumes of octan-1-ol with chloroform, 1,2-dichloroethane and 1,1,2,2-tetrachloroethane at 298.15 and 308.15 K

“…An exactly similar type of behaviour has also been observed for the variation of V E with mole fraction for the binary mixtures of 1,2-DCE þ heptanol and 1,1,2,2-TCE þ heptanol [1,6]. The magnitude of the maximum value of V E increases slightly with the increase of temperature from 298.15 to 308.15 K. The observed positive V E values may be explained in terms of physical, chemical and structural factors [4,8,10,13,28,29,[37][38][39][40][41]. The positive contribution might be due to the physical forces involving dispersive interactions between unlike molecules.…”

Study of intermolecular interactions in binary mixtures of cyclohexane with 1-alkanols at 308 k

“…Thus, we conclude that the behaviour of V E with x is well reflected in the behaviour of ÁK s for all the binary mixtures investigated. Similar behaviour was also reported by Ali et al [24] for DMSO þ 1-hexanol/1-octanol and by Fort and Moore [25] for benzene þ cyclohexane binary systems. The relative values of V E and ÁK s (Figs.…”

The Sound Velocity in Ideal Liquid Mixtures from Thermal Volume Fluctuations

“…[39] Furthermore, also data sets from a number of more recent publications, proposed by Glinski, [8] were used. [40][41][42][43][44][45][46][47] However, we did not determine the average deviations per mixture, but we used every pair of sound velocity and density given in the corresponding tables. By this procedure, we obtained about 1000 pairs of deviations of sound velocity and excess volume, which are shown in Figure 3.…”
