Abstract:

To improve volumetric properties of straight chain alkanes which is the main component in petroleum hydrocarbon fuels, exo-tetrahydrodicyclopentadiene(JP-10) was grouped into five binary systems with n-nonane, n-undecane,n-dodecane, n-tridecane and n-tetradecane, respectively. The densities and viscosities were determined over the whole composition range for the binary mixtures at different temperatures(293.15, 298.15, 303.15 and 313.15 K) by Anton Paar DMA5000 M and Anton Paar AMVn. The volumetric properties of mixtures were calculated according to the obtained data. The molecular structure and intermolecular interactions were qualitatively discussed. Thermodynamic functions of activation of the binary systems were calculated according to the absolute rate theory approach of Eyring, which indicate ΔH^≠ plays a major role. The results may provide important information for the blending of hydrocarbon fuels.
