正丁醇/正戊醇+JP-10二元体系的体积性质

Volumetric Properties of Binary Systems of n-Butanol or n-Pentanol+JP-10

在常压下测定了298.15 K时正丁醇/正戊醇+挂式四氢双环戊二烯(C10H16,JP-10)二元体系的黏度和密度.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,焓驱动起主要作用.利用密度数据计算了醇+JP-10二元体系的超额摩尔体积、超额偏摩尔体积、表观摩尔体积及偏摩尔体积等体积性质,结果表明此二元体系的超额摩尔体积为正值.

The kinematic viscosities and densities of the binary mixtures of n-butanol/n-pentanol＋JP-10（exo-tricycle[5.2.1.02.6]decane,C10H16） were determined at 298.15 K via Ubbelohde viscometer and Anton PaarDMA55 vibrating-tube digital densimeter.Thermodynamic functions of activation of the binary systems were calculated according to the absolute rate theory approach of Eyring,which indicate ΔH0≠ plays a major role.Excess molar volumes,excess partial molar volumes,apparent molar volumes and partial molar volumes were calculated based on the densities data.The results indicate that VEm of the binary systems are positive.
