Densities, viscosities, and refractive indices have been measured for the binary system of tricyclo[5.2.1.0(2.6)]decane with cyclohexane, methylcyclohexane, ethylcyclohexane, butylcyclohexane, or 1,2,4-trimethylcyclohexane at temperatures T = (293.15 to 318.15 K) and pressure p = 0.1 MPa. The excess molar volumes (V-m(E)), the viscosity deviations (Delta eta), and the refractive index deviations (Delta n(D)) are then calculated. The changes of V-m(E) and Delta eta with the composition are fitted to the Redlich-Kister equation. The values of density, viscosity, and refractive index increase continuously with the increase of mole fraction of tricyclo[5.2.1.0(2.6)]decane and decrease with the rise of temperature. The V-m(E) and Delta eta are all negative over the whole composition range for these five binary systems. The changes of V-m(E) and Delta eta are discussed from the points of view of molecular interactions in the binary systems.
