甲苯－乙醇－正己烷（四氯化碳）三元体系过量焓

Excess enthalpies of ternary system of toluene-ethanol-hexane or tetrachloromethane

使用流动式微量热计测量了２９８．１５Ｋ下甲苯－乙醇－正己烷和甲苯－乙醇－四氯化碳两组三元体系以及正己烷－乙醇、乙醇－甲苯、正己烷－甲苯、四氯化碳－甲苯和四氯化碳－乙醇五组二元体系过量焓，对实测数据进行了关联，并计算了全浓度范围内过量焓，绘制了三元体系的等过量焓图。

Excess molar enthalpies,measured at 298. 15 K in a flow microcalorimeter ,are reported for the ternary mixtures(toluene-ethanol-hexane and toluene-ethanol-tetrachloromethane), and also for the binary mixtures(hexane-ethanol,ethanol-toluene, hexane-toluene,tetrachloromethane-toluene and tetrachloromethane-ethanol). The data measured are correlated and the excess ethalpies in full concentrations are calculated. The constant excess enthalpy contours for the ternary systems are also given.
