Abstract

The density ( ), viscosity ( η ) and ultrasonic velocity (U) have been measured for the binary mixtures of dimethyl sulfoxide with methanol, ethanol, propan-l-ol and butan-l-ol over the entire range of mole fractions at a constant temperature of 308.15 K. Excess molar volume (VE), deviation in viscosity ( Δη ) and deviation in isentropic compressibility ( ΔKs) are calculated and related to intermolecular interactions.
