Densities, Viscosities and Speeds of Sound of Binary Mixtures of Stereoisomeric Decalins

Densities, viscosities and speeds of sound for the binary mixture of cis- and transdecalins have been measured over the whole composition range at 293.15 K and 305.15 K. The limiting partial volumes, excess volumes, deviations in viscosity and isentropic compressibilitywere calculated. It appeared that the mixture of stereoisomeric decalins is characterized by a moderate excess volume and relatively small deviations in viscosity and isentropic compressibility. The results were fitted to the Redlich – Kister equation.
