ABSTRACT

Excess volumes (VE) ultrasonic sound velocities (u), isentropic compressibilities (Ks) and viscosities (g) have been measured for the binary mixtures of dimethylsulphoxide (DMSO) with 1,2-dichlorobenzene, 1,3-dichlorobenzene, 1,2,4-trichlorobenzene, o-chlorotoluene, m-chlorotoluene, p-chlorotoluene, o-nitrotoluene and m-nitrotoluene at T = 303.15 K. The measured VE values were positive over the entire composition range in all the binary mixtures. Isentropic compressibilities (Ks) have been computed for the same systems from precise sound velocity and density data. Further, deviation in isentropic compressibility (DKs) from ideal behaviour was also calculated. The viscosity data are analysed on the basis of corresponding states approach. Deviation in viscosities are positive over the entire composition range. The measured data is explained on the basis of intermolecular interactions between unlike molecules.
