文摘
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, VmE, the viscosity deviations, 螖畏, and the surface tension deviations, 螖纬, for these binary systems are calculated and fitted to the Redlich鈥揔ister equation, and the regression coefficients and the standard deviations of the fittings are given. All of the VmE, 螖畏 and 螖纬 values are negative over the whole composition range for these systems. The values of 螖nD for these binary mixtures are all small, even negligible. These results may be useful for the development of the hydrocarbon fuels.
