Densities and Viscosities for the Ternary Mixtures of <i>exo</i> -Tetrahydrodicyclopentadiene (1) + Methyl Decanoate (2) + 1-Pentanol (3) and Corresponding Binaries at <i>T</i> = (293.15 to 333.15) K and <i>p</i> = 0.1 MPa

It has been proven that biofuels could enhance the performance of endothermic hydrocarbon fuels (EHFs) such as reducing harmful emissions and adjusting physical properties. In order to understand the properties of EHFs containing biofuels, the densities (ρ) and viscosities (η) of the ternary system exo-tetrahydrodicyclopentadiene (1) + methyl decanoate (2) + 1-pentanol (3) and the corresponding binary systems were investigated at T = (293.15 to 333.15) K and p = 0.1 kPa. The excess molar volume (VmE) and viscosity deviation (Δη) of the binary mixtures were calculated and fitted into the Redlich–Kister equation. The VmE and Δη of the ternary system were calculated and fitted to four different semiempirical equations (Singh, Cibulka, Nagata–Tamura, and Redlich–Kister). The results show that all VmE values of binary systems and ternary system are positive while all Δη values are negative. This work can provide reliability data for the compatibility of biofuels and EHFs.
