乙醇－乙酸丁酯二元系统的等温气液平衡

摘要本文应用液上气相色谱法测定了乙醇－乙酸丁酯二元系统在３０．０℃，４０．０℃、４５．０℃下的气液平衡数据，在此温度范围内的数据未见文献发表。本文所测气液平衡数据经Ｈｅｒｉｎｇｔｏｎ法校验均满足热力学一致性要求。采用单纯形法优化出该二元系统在３０．０℃～８０．０℃范围内的ＮＲＴＬ模型参数，拟合中将文献［１］中６０．０℃、７０．０℃，８０．０℃的数据与本文数据一起关联，并把ＮＲＴＬ模型参数表示为温度的线性函数。拟合结果精度较高。

Abstract： Isothermal VLE data for ethanol-n-butyl acetate binary systerm at30.0℃,40.0℃,45.0℃ have been determined by using the method of head space chromatography,Thermodynamic consistency of T-x-y data in the present work has been tested by means of the Herington method and has satisfied the requirement.The parameters of NRTL model for this binary system in the range of 30.0～80.0℃,expressed as function of the temperature, have been optimized by simplex method.

Keywords： s: ethanol n-butyl acetate head space chromatography vapor-liquid equilibrium
