摘要
通过差示扫描量热法测定了2,6-二氯硝基苯-2,3/3,4-二氯硝基苯2个二元体系的固液相平衡数据,绘制出相应的共熔型二元相图,采用NRTL方程对固液平衡数据进行关联。关联结果表明:NRTL方程对固液平衡数据关联精度较高,2个二元体系共晶点的2,6-二氯硝基苯的摩尔分数分别为0.5000和0.3000,最低共熔温度分别为308.55 K和294.45 K。
The solid-liquid equilibrium data of two binary systems of 2,6-dichloronitrobenzene-2,3/3,4-dichloronitrobenzene were determined by differential scanning calorimetry with corresponding eutectic binary phase diagram presented.The solid-liquid equilibrium data was fitted by NRTL equation.The results show that NRTL equation can provide good correlation,the molar fraction of 2,6-dichloronitrobenzene in the eutectic point of the two binary systems are 0.5000 and 0.3000,respectively and the minimum eutectic temperatures are 308.55 K and 294.45 K,respectively.
