Résumé / Abstract

Density and ultrasonic velocity were measured in pure N,N-dimethylacetamide (DMA), 1-hexanol, 1-octanol, chlorobenzene, toluene, and in their binary mixtures with DMA as common component, at 303.15 K. The dependence of u on mole fraction of DMA was represented by empirical equation. From the experimental data, the values of adiabatic compressibility, intermolecular free length, relative association, acoustic impedance, molar sound velocity, excess adiabatic compressibility, excess volume and molecular association in four binary systems were obtained. These parameters are used here to discuss the nature and extent of molecular interactions in the mixtures. The experimental values of ultrasonic velocity have been compared with those predicted on the basis of free length theory (FLT), collision factor theory (CFT), and Nomoto's relation, and the merits of these theories and relations are discussed.
