Abstract
Abstract New experimental data for excess volume and sound velocity in binary liquid mixtures of 1,2-dibromoethane with methyl ethyl ketone, diethyl ketone, methyl propyl ketone, methyl isobutyl ketone, cyclopentanone and cyclohexanone at 303.15 K have been reported. The results have been analysed in terms of free length theory (FLT) and collision factor theory (CFT). Molar sound velocity (R), molar compressibility (W) and van der Waals constant (b) have also been computed. The sound velocity data were also used along with densities to compute isentropic compressibilities (ks). The excess volumes (VE) and the deviation in isentropic compressibilities (Δks) are used to understand the interactions between unlike molecules.
