Densities (ρ), ultrasonic speeds of sound (u) of binary mixtures containing propiophenone with o-xylene,m-xylene and p-xylene were measured over the entire composition range at temperatures from303.15-318.15 K and at atmospheric pressure 0.1 MPa. Experimental data of ultrasonic velocity wasused to compute the theoretical velocities by using the various theories like Nomoto’s relation (UNOM),impedance relation (UIMP), Van Dael and Vangeel’s relation (UVDV), Rao’s specific velocity relation(URAO), Jouyban-Acree’s (UJOE) and Junjie’s theory (UJUN). The results are in good agreement with theexperimental data. The relative percentage error, chi square test for goodness of fit and the molecularinteraction parameter (α) values for non-ideality in the binary mixtures were computed and analyzedin terms of intermolecular interactions between the molecules of the binary mixtures.
