水+异戊醇+乳酸异戊酯三元液液相平衡的测定与关联

DETERMINATION AND CORRELATION OF TERNARY LIQUID-LIQUID EQUILIBRIUM OF WATER,ISOAMYL ALCOHOL AND ISOAMYL LACTATE

测定了常压下水+异戊醇+乳酸异戊酯三元混合体系在293.15 K、313.15 K、333.15 K温度下的液液相平衡数据,并与文献中已有的水+异戊醇二元液液相平衡数据进行比较,验证了测定方法的可靠性。利用Othmer–Tobias、Bachman和Hand方程验证了实验数据的可靠性。利用NRTL与UNIQUAC模型对数据进行关联,获得了模型的二元交互作用参数,关联结果与实验数据一致。

Liquid-liquid equilibrium data of the ternary mixed system of water,isoamyl alcohol and isoamyl lactate were determined respectively at 293.15,313.15,333.15 K under atmospheric pressure.Reliability of the determination method was verified by comparing with the binary liquid-liquid equilibrium data of water and isoamyl alcohol in the literature.Othmer-Tobias,Bachman and Hand equations were used to verify reliability of the experimental data.NRTL and UNIQUAC models were used to correlate the experimental results,and the binary interaction parameters were obtained.The correlation results obtained from the models were consistent with the experimental data.
