硝基氯苯体系固液平衡研究

摘要利用差式扫描量热法,测定了硝基氯苯同分异构体二元及三元固液平衡 t—x关系。同时,利用表征分子特征的拓扑指标θ关联溶液的过量自由能 G~E。计算了二元及三元硝基氟苯同分异构体的固液平衡。G~E 方程式为G~E=RT 式中 k_(ij)为通过实验确定的两分子相互作用参数。上式计算值与实验值的偏差小于2K。

Abstract： The binary and ternary solid-liquid equilibria (t-x) for nitrochlorobenzeneisomer systems had been determined by differential scanning calorimetry.Inaddition,using the equation of excess Gibbs energy G~E which was correlatedwith the topological index,the binary and ternary solid-liquid equilibria (t-x) for nitrochlorobenzene isomer systems were calculated.The G~E equation isG~E=RT where k_(ij) is an adjustabte parameter between two molecularity determinedby exeperiment.By this equation the maximum deviation between T_(cal) andT_(exp) is tess than 2K.
