摘要:

利用Anton PaarDMA55和Ubbelohde黏度管分别测定了正辛烷和正癸烷两种正构烷烃与挂式四氢双环戊二烯{C10H16, exo-tricycle[5.2.1.02.6]decane(JP-10)}组成的二元体系在298.15 K下的密度和黏度, 计算了正构烷烃/JP-10二元体系的超额摩尔体积、组分的表观摩尔体积和偏摩尔体积等体积性质以及组分对超额体积的贡献, 研究结果表明, 烷烃的加入使得二元体系的超额体积均为负值. 根据Eyring液体黏性流动理论, 关联了二元体系的黏滞性活化参数, 结果表明, 熵驱动起主要作用. 从分子间相互作用角度讨论了二元体系体积性质的变化规律.

Abstract:

The densities and viscosities of the binary mixtures of n-octane/JP-10 and n-decane/JP-10 were determined at 298.15 K by the Anton Paar vibriating-tube densimeter and Ubbelohde viscometer, over the entire composition range. Excess molar volumes, apparent molar volumes, partial molar volumes and the contribution to the excess volume of the components were calculated. The experimental data indicate that the addition of n-alkane has a distinct effect on the density and viscosity of JP-10 and VmE of the binary systems are negative.Thermodynamic functions of activation of the binary systems were calculated according to the absolute rate theory approach of Eyring, which indicate ΔS0≠ plays a major role. Conclusions were qualitatively discussed in terms of molecular interactions, which provide important information on the research and application of JP-10 and blended fuel.
