ABSTRACT

For a comprehensive understanding of the properties of 1,3-dimethyladamantane (1,3-DMA) as a new potential candidate of high energy-density hydrocarbon fuels, densities, viscosities, surface tensions, and refractive indices for binary mixtures of 1,3-DMA with each of four C10 alkanes, n-decane, butylcyclohexane, decalin, and exo-tetrahydrodicyclopentadiene (JP-10), are determined over the whole composition range at different temperatures ranging from (293.15 to 363.15) K and atmospheric pressure (0.1 MPa). The excess molar volume (VmE), the viscosity deviation (??), the surface tension deviation (??), and the refractive index deviation (?nD) for these binary systems are calculated. All of the VmE values are negative over the whole composition range for these systems, and they show slight changes against the temperature. The ?? values for the systems except 1,3-DMA + JP-10 are negative, and the absolute values decrease obviously with rising temperature. The ?? gives clearly negative values for the system of 1,3-DMA + n-decane and shows small values near zero for the other systems. Negligible values of ?nD indicate that the refractive indices show nearly linear additions from those of two components for the binary mixtures. The results could provide important reference information for the development and performance of new high energy-density hydrocarbon fuels.
