Measurements of density, viscosity and vapor pressure for binary mixtures of exo-tetrahydrodicyclopentadiene (JP-10) with isopropyl ether are reported at temperatures of (293.15, 298.15, 303.15, 308.15, and 313.15) K over the entire composition range. The excess molar volumes, viscosity deviation and excess Gibbs energies of activation for the binary systems were calculated from the experimental values and fitted with the Redlich-Kister equation. Isopropyl ether was added to enhance the vapor pressure of JP-10. Experimental vapor pressure data were correlated by the Antoine equation. Several semi-empirical equations were used to correlate the viscosity data. The McAllister equation gives relatively satisfactory results for the correlation. The experimental and correlated data could be used in the development of models for mixtures of hydrocarbons with oxygenates. [ABSTRACT FROM AUTHOR]

Abstract: The densities and viscosities of mixtures of a hydrocarbon fuel (JP-10) with methyl tert-butyl ether (MTBE) or ethyl tert-butyl ether (ETBE) were determined at different temperatures (293.15, 298.15, 303.15, 308.15 and 313.15)K, over the entire composition range. Excess molar volumes, viscosity deviation and excess Gibbs energies of activation of mixtures were calculated and fitted to the Redlich–Kister equation. The excess molar volumes are negative over the entire range of composition. The viscosity data have been correlated with several semi-empirical equations. The thermodynamic functions of activation were also calculated. The refractive indices of the systems were also measured for temperatures of (293.15, 303.15 and 313.15)K. The results provide important information on the research and application of JP-10 and fuel ethers as additives. [Copyright &y& Elsevier]
