【摘要】 测定了水-仲丁醇-乙酸仲丁酯三元体系在303.15,323.15,343.15,353.15 K下的液液相平衡数据,并用NRTL模型和UNIQUAC模型对相平衡数据进行关联,应用单纯形法求得相应的模型参数。计算值与实验值比较结果表明:NRTL模型与UNIQUAC模型的计算值与实验数据吻合良好。更多还原

【Abstract】 Liquid-liquid equilibrium(LLE) data of the water +sec-butyl alcohol + sec-butyl acetate ternary system were measured at 303.15 K,323.15 K,343.15 K and 353.15 K under atmospheric pressure.The active coefficients in the LLE equations were calculated by the NRTL and UNIQUAC models,and the calculated LLE data of water +sec-butyl alcohol + sec-butyl acetate ternary system were compared with the experimental data. Based on the NRTL and UNIQUAC models,the calculated equilibrium compositions of the studied ternary system are in good agreement with the experimental data.更多还原
