Excess sound velocity and excess specific acoustic impedance of (2,2,2-trifluoroethan-1-O1+benzene), (benzene plus dimethyl sulphoxide) and (2,2,2-trifluoroethan-1-O1+dimethyl sulphoxide) at 298.15 K

摘要

Excess sound velocity (U-E) and excess specific acoustic impedance (Z(E)) have been evaluated in binary liquid mixtures: 2.2,2-trifluoroethan-1-O1 +benzene, benzene + dimethyl sulphoxide and 2,2,2-tritluoroethan-1-O1+dimethyl sulphoxide at 298.15 K. The results are discussed in the light of molecular interactions in these mixtures and compared with the other excess thermodynamic data available in literature. The liquid state theories have been applied to predict the sound velocities in these mixtures. [References: 23]
