Abstract:

The densities and viscosities of the binary mixtures of n-octane/JP-10 and n-decane/JP-10 were determined at 298.15 K by the Anton Paar vibriating-tube densimeter and Ubbelohde viscometer, over the entire composition range. Excess molar volumes, apparent molar volumes, partial molar volumes and the contribution to the excess volume of the components were calculated. The experimental data indicate that the addition of n-alkane has a distinct effect on the density and viscosity of JP-10 and V_m^E of the binary systems are negative.Thermodynamic functions of activation of the binary systems were calculated according to the absolute rate theory approach of Eyring, which indicate ΔS^0≠ plays a major role. Conclusions were qualitatively discussed in terms of molecular interactions, which provide important information on the research and application of JP-10 and blended fuel.
