exo-Tetrahydrodicyclopentadiene can serve as both the propellant and coolant in hypersonic vehicles. However, its applications are restricted by the poor properties of ignition and combustion to some extent. Fuel additives such as appropriate alcohols have the ability to overcome these deficits. Research on thermophysical properties of the mixtures composed of exo-tetrahydrodicyclopentadiene and fuel additives can provide important information for the research of fuel additives. In this work, densities and viscosities of the ternary system of exo-tetrahydrodicyclopentadiene (1) + n-decane (2) + iso-butanol (3) and three corresponding binary systems have been measured over the whole composition range in the temperature range from 293.15 to 333.15 K with an interval of 5 K and at pressure p = 0.1 MPa. The values of excess molar volumes (V_m^E) and viscosity deviations (Δη) of three binary systems and the ternary system were calculated and then fitted to the Redlich–Kister equation and four semi-empirical equations, respectively. The variations of V_m^E and Δη were explained from the viewpoints of intermolecular forces and structural effects. Furthermore, the Jouyban–Acree model was used to correlate the values of densities (ρ) and viscosities (η) of the studied mixtures with high accuracy.

外-四氢二环戊二烯（1）+正癸烷（2）+异丁醇（3）和相应的二元体系三元体系的密度和粘度测量

exo- Tetrahydrodicyclopentadiene可以在高超音速飞行器中同时用作推进剂和冷却剂。但是，其应用受到点火和燃烧性能差的限制。燃料添加剂（例如适当的醇）具有克服这些缺陷的能力。研究由外-四氢二环戊二烯和燃料添加剂组成的混合物的热物理性质可以为燃料添加剂的研究提供重要的信息。在这项工作中，外-四氢二环戊二烯（1）+ n的三元体系的密度和粘度在整个组成范围内，在293.15至333.15 K的温度范围内，以5 K的间隔和压力p = 0.1 MPa测量了癸烷（2）+异丁醇（3）和三个相应的二元体系。计算了三个二元体系和三元体系的过量摩尔体积（V _m^E）和粘度偏差（Δη）的值，然后分别拟合到Redlich-Kister方程和四个半经验方程。从分子间力和结构效应的角度解释了V _m^E和Δη的变化。此外，Jouyban-Acree模型用于高精度地关联所研究混合物的密度（ρ）和粘度（η）值。
