文摘

Measurement of densities (蟻), ultrasonic sound speeds (u) and viscosities (畏) has been carried out for binary mixtures of N,N-dimethylaniline (N,N-DMA) with acetone(AC), methylethylketone (MEK), methylpropylketone (MPK), diethylketone (DEK), methylisobutylketone (MIBK), acetophenone (AP), cyclopentanone (CP), cyclohexanone (CH) and 2-methylcyclohexanone (MeCH) and their pure liquids at (303.15 K and 308.15) K over the entire composition range. These experimental data have been used to calculate the excess molar volume (V^E), deviation in ultrasonic sound velocity (螖u), deviation in isentropic compressibility (螖魏_s) and deviation in viscosity (螖畏) were evaluated. The variation of these properties with composition of the mixtures suggests dipole-dipole interactions and charge transfer complex formation between N,N-dimethylaniline and ketones. The magnitude of the property is found to depend on the chain length of the ketones molecule. These results have been fitted to the Redlich-Kister polynomial equation. The viscosity data have been correlated using three equations; Grunberg and Nissan, Katti and Chaudhri, Hind et al. for the system studied.
