Ultrasonic velocity and density have been measured in the binary mixtures of acetophenone and NN-dimethylformamide with benzyl benzoate as common component at three temperatures 30, 40 and 50°C. Adiabatic compressibility, free length, molar volume etc. have been calculated and the excess parameters of these are employed for estimating the molecular interactions in the mixed state. Mostly strong and dipole-dipole interactions are indicated in the acetophenone and dimethylformamide systems at all concentrations. In both the systems endothermic type of reactions is suggested. From a theoretical evaluation of velocities, CFT, NOMOTO and JUNJIE appear to have an edge.

Abstract


Ultrasonic velocity and density have been measured in the binary mixtures of acetophenone and NN-dimethylformamide with benzyl benzoate as common component at three temperatures 30, 40 and 50°C. Adiabatic compressibility, free length, molar volume etc. have been calculated and the excess parameters of these are employed for estimating the molecular interactions in the mixed state. Mostly strong and dipole-dipole interactions are indicated in the acetophenone and dimethylformamide systems at all concentrations. In both the systems endothermic type of reactions is suggested. From a theoretical evaluation of velocities, CFT, NOMOTO and JUNJIE appear to have an edge.
