Densities and viscosities have been measured over the whole composition ranges for the binary mixtures of 2,2,4-trimethylpentane with methylcyclohexane, ethylcyclohexane, or n-butylcyclohexane at temperatures T = (293.15 to 343.15) K and atmospheric pressure. Meanwhile, the refractive indices and surface tensions were measured at T = (293.15 to 323.15) K and T = (293.15 to 308.15) K, respectively. The excess molar volumes, V-m(E), the viscosity deviations, Delta eta, and the surface tension deviations, Delta gamma, for these binary systems are calculated and fitted to the Redlich-Kister equation, and the regression coefficients and the standard deviations of the fittings are given. All of the V-m(E), Delta eta and Delta gamma values are negative over the whole composition range for these systems. The values of Delta n(D) for these binary mixtures are all small, even negligible. These results may be useful for the development of the hydrocarbon fuels.
