Excess molar volume along with viscosity, refractive index and relative permittivity for binary mixtures of exo-tetrahydrodicyclopentadiene with four octane isomers

The fundamental physical properties including density, viscosity, refractive index and relative permittivity, have been measured for binary mixtures of exo-tetrahydrodicyclopentadiene (JP-10) with four octane isomers (n-octane, 3-methylheptane, 2,4-dimethylhexane and 2,2,4-trimethylpentane) over the whole composition range at temperatures T = (293.15 to 313.15) K and pressure p = 0.1 MPa. The values of excess molar volume VmE, viscosity deviation (Δη), refractive index deviation (ΔnD) and relative permittivity deviation (Δεr) are then calculated. All of the values of VmE and Δη are observed to be negative, while those of ΔnD and Δεr are close to zero. The effects of temperature and composition on the variation of VmE values are discussed. The negative values of VmE and Δη are conductive to high-density and low-resistance of fuels, which is favorable for the design and preparation of advanced hydrocarbon fuels.
