Biofuel mixed with fossil jet fuels has a lot of potential in applications of jet fuel extenders. To understand the fundamental properties of this typical mixture, measurements on densities and viscosities for the ternary model system of exo-tetrahydrodicyclopentadiene (1) + isopropylcyclohexane (2) + methyl laurate (3) and three corresponding binary mixtures have been implemented over the entire composition range at eleven different temperatures from 293.15 to 343.15 K. The excess molar volumes (V-m(E)) and viscosity deviations (Delta(eta)) of binary mixtures were calculated and correlated by the Redlich-Kister equation, while the corresponding data of ternary mixtures were fitted to Nagata-Tamura, Cibulka, Singh, and Redlich-Kister equations. Furthermore, the variations of V-m(E) and Delta(eta) were represented and discussed based on molecular interactions and structural effects in detail.
