The densities and dynamic viscosities of three binary liquid mixtures of tricyclo [5.2.1.02,6] deca-3,8-diene(endo-DCPD) with ethanol, 2-propanol and 1-pentanol at different temperatures (293.15, 303.15 and 313.15) K and atmospheric pressure were measured over the entire compositional range. The excess molar volume, viscosity deviation and excess Gibbs energy for activation of the viscous flow of mixtures were calculated and adjusted by the Redlich–Kister equation. The excess molar volume data were correlated using Prigogine–Flory–Patterson (PFP) theory. Five typical semi-empirical correlations with one and two interaction parameters and predictive models UNIFAC Dortmund_VISCO (Universal Functional Activity Coefficients modified by Dortmund-Viscosity) and ASOG_VISCO (Analytical Solution Group-Viscosity) with newly estimated interaction parameters were used to correlate viscosity. In addition, excess Gibbs free energy results were estimated using local composition concept and group contribution models. All of these results provide important information on the research and application of high-density jet fuel with green fuel as additives.
