Abstract
Isentropic compressibilities for binary liquid mixtures of cyclohexanone with n-hexane, n-heptane, 2,2,4-trimethylpentane, benzene, toluene and tetrachloromethane have been computed using measured density and sound velocity data at 298.15 K. Excess isentropic compressibilities exhibit an inversion in sign in the system cyclohexanone with toluene and in the remaining systems the excess property is negative over the entire range of composition studied. The results have been discussed in terms of the difference in molecular size and shape of the components, and specific interactions between unlike molecules.
