Densities and viscosities of binary liquid mixtures of N-methylacetamide with some chloroethanes and chloroethenes at T=308.15K

“…The studies of excess properties such as excess molar volume (V E ), deviation in viscosity (Dg), excess Gibbs free energy of activation of viscous flow (G ÃE ) and Grunberg-Nissan interaction constant (d 0 ) of binary mixtures are useful in understanding the nature of inter molecular interactions between two liquids. Jan Zielkiewicz [1] has reported excess volumes of the binary and ternary mixtures containing N-methylacetamide, water and ethanol at T = 313.15 K while Naidu et al [2] have studied excess volumes and excess viscosities for the mixtures of ethylene glycol, triethylene glycol, poly(ethylene glycol)-200 and poly(ethylene glycol)-300 with N-methylacetamide at T = 308.15 K. Victor and Hazra [3] have determined excess molar volumes, viscosity deviations and isentropic compressibility changes for binary mixtures of N-methyl-acetamide with 2-methoxyethanol and water at T = (308.15 to 318.15) K while Rao et al [4] have studied the ultrasonic studies for binary mixtures of N-methylacetamide with glycols at T=308.15 K. Tangeda and Nallani [5,6] have investigated excess molar volumes, viscosity deviations and isentropic compressibilities for (N-methylacetamide + aromatic ketone) systems at T = 308.15 K.…”
