چکیده انگلیسی

Excess volume (VE  ), excess isentropic compressibility (κSE) and deviation in viscosity (Δη) were studied for eight binary systems of dimethylacetamide (DMA) with 1,2-dichlorobenzene, 1,3-dichlorobenzene, 1,2,4-trichlorobenzene, o-chlorotoluene, m-chlorotoluene, p-chlorotoluene, o-nitrotoluene and m-nitrotoluene in the entire composition range at 303.15 K and atmospheric pressure. Excess volume data for the studied mixtures were measured directly using a single composition loading type dilatometer and compared with predictive expressions proposed by Redlich–Kister and Hwang. Moreover, the VE data in the present investigation were analyzed by using Prigogine–Flory–Patterson (PFP) theory. The speed of sound data was measured with a single crystal interferometer at a frequency of 3 MHz and data were analyzed in terms of free length theory (FLT) and collision factor theory (CFT). Experimental viscosity data were measured by a suspended Ubbelohode-type viscometer, which in turn used to calculate deviation in viscosity and interaction parameters for various models such as Gruenberg–Nissan, Tamura and Kurata and Hind et al. The experimental data were discussed on the basis of intermolecular interactions between unlike molecules.
