Abstract
Density (ρ) and speed of sound (u) data have been measured at temperatures 303.15 and 313.15K and at atmospheric pressure for five binary mixtures of aniline with chlorobenzene, bromobenzene, 1,2-dichlorobenzene, 1,3-dichlorobenzene and 1,2,4-trichlorobenzene over the entire composition range. Experimental density and speed of sound data have been used to calculate the excess volumes (VE), isentropic compressibilities (κs) and excess isentropic compressibilities (κsE) of studied mixtures. The calculated VE data were correlated with Redlich–Kister and Hwang polynomial equations. The experimental speed of sound data were analyzed in terms of Schaaff's collision factor theory (CFT) and Jacobson's free length theory (FLT). Results, obtained by measurements as well as calculations, were discussed in terms of intermolecular interactions between component molecules.
