Density and viscosity measurements are reported for the binary mixtures of some cyclic ethers (tetrahydrofuran, tetrahydropyran, 2-methyl-tetrahydrofuran and 2,5-dimethyl-tetrahydrofuran) with chlarocyclohexane at 298.15 K and 313.15 K. The viscosity data were correlated by the equations of Grunberg-Nissan, McAllister, and Heric. The experimental data were used to calculate excess volumes and viscosity deviations, and the results were fitted to a Redlich-Kister type equation.
