摘要
用自行设计的平衡釜测定了邻、间、对硝基氯苯三元体系于100mmHg 柱恒压下的汽液平衡数据。根据热力学相平衡原理,计算出各组分液相活度系数,证明了该三元体系为完全理想系.另外又通过牛顿迭代法计算出平衡温度和汽相组成,计算结果和实测数据符合良好,能够满足工程设计的需要。
Vapour—liquid equilibrium data of ortho-,meta-,para-nitrochlo-robenzene ternary system are determined under 100mm Hg pressure by the equilibrium still designed by ourselves.According to the thermody-namic principle of phase equilibrium,activity coefficents of liquid compostions of all items are calculated,proving that the ternary system is ideal.Besides,equilibrium temperature and compositions of vapour are calculated by Newton-Raphson method.The calculated results and the determined data are in a good agreement,being able to satisfy the demands of engineering designs.
