Measurements on densities, viscosities, and refractive indices at atmospheric pressure for binary mixtures of 1,3-dimethyladamantane (1,3-DMA), 1,3,5-trimethyladamantane (1,3,5-TMA), and 1-ethyladamantane (1-EA) with n-nonane or n-undecane are carried out over the whole composition range at temperatures T = 293.15–343.15 K and atmospheric pressure. The excess molar volume (VmE), deviation in viscosity (Δη), deviation in refractive index (ΔnD), and deviation in molar refraction (ΔR) for the six mixtures are calculated and then fitted to the Redlich–Kister polynomial. The VmE values are all negative over the entire range of mole fractions and decrease with increasing temperature for the six binary systems. The absolute values of Δη for the mixtures decrease obviously with increasing temperature. The ΔnD values with the volume fraction for the six systems are all positive over the entire composition range. Density, viscosities, and refractive index of the six systems are correlated by the Jouyban–Acree model. The experimental results could be useful for the development of high-energy-density hydrocarbon fuels.

T = 293.15–343.15 K和大气压下三种正金刚烷衍生物与壬烷或十一烷的二元混合物的密度,粘度和折射率

1,3-二甲基金刚烷(1,3-DMA),1,3,5-三甲基金刚烷(1,3,5-TMA)和1-乙基金刚烷的二元混合物在大气压下的密度,粘度和折射率的测量在温度T = 293.15–343.15 K和大气压下,在整个组成范围内进行具有壬烷或十一烷的(1-EA)反应。计算出六种混合物的过量摩尔体积(V m E),粘度偏差(Δη),折射率偏差(Δn D)和摩尔折射率偏差(ΔR),然后将其拟合到Redlich–Kister多项式。的Vë对于六个二元体系,在整个摩尔分数范围内,该值均为负,并随温度的升高而降低。混合物的Δη绝对值随温度升高而明显降低。该Δ Ñ d值与用于六个系统的体积分数是遍布整个组合物范围内的正。Jouyban-Acree模型将六个系统的密度,粘度和折射率关联起来。实验结果可能对开发高能量密度的烃类燃料有用。
