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 (V-m)(E) , viscosity deviation (Delta eta), refractive index deviation (Delta n(D) ) and relative permittivity deviation (Delta epsilon(r)) are then calculated. All of the values of V-m(E) m and Delta eta are observed to be negative, while those of DnD and Der are close to zero. The effects of temperature and composition on the variation of V-m(E) m values are discussed. The negative values of V-m(E) m and Delta eta are conductive to high-density and low-resistance of fuels, which is favorable for the design and preparation of advanced hydrocarbon fuels.
