Densities and viscosities of binary mixtures of JP-10 with n-octane or n-decane at several temperatures

The densities and viscosities of the binary mixtures of JP-10 + n-octane and JP-10 + n-decane were determined from T = 293.15 K to T = 3 13.15 K at atmospheric pressure, over the entire composition range. Excess volume V-m(E) of the binary mixtures was 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) values of the binary systems are negative. Experimental data were fitted to the Redlich-Kister equation, and the adjustable parameters and the standard deviations between experimental and calculated values were estimated. Conclusions were qualitatively discussed in terms of molecular interactions. The viscosity data have been correlated with several semiempirical equations, and the Grunberg-Nissan equation gives satisfactory results.
