摘要
用循环式玻璃釜测定了101.33 kPa,66.66 kPa和40.00 kPa下的乙酸乙酯-吡啶体系的汽液平衡,用Herington面积检验法则检验结果表明,实验数据满足热力学一致性。分别用Wilson和NRTL活度系数模型关联了实验数据,两者结果较为接近,汽相组成和泡点温度的最大误差分别为0.0075和0.29℃。
Vapor liquid equilibrium data for system of ethyl acetate-pyridine at the pressures of 101.33 kPa, 66.66 kPa and 40.00 kPa were determined with a circulating glass still. The experimental data at different pressures satisfied the requirement of Herington抯 thermodynamic consistency. Those data were also correlated by Wilson and NRTL activity coefficient models, equivalent results were obtained, the maximum deviations of calculated vapor composition and bubble temperature from those of experimental were 0.0075 and 0.29℃ respectively.
