The intention of this article is to clarify some concepts and relevant aspects of the experimental determination and treatment of liquid–liquid equilibrium data for ternary systems. Distinction is made between solubility curve and binodal curve, setting the stability limit which is defined by the spinodal curve. In addition, it is recommended to carry out the equilibrium data correlation using semiempirical models with a thermodynamic base, over the use of empirical equations. Moreover, the misuse of these empirical equations (Hand, Bachman, Othmer-Tobias, etc.) as proof of data quality or consistency is clarified.

修订液-液萃取概念：数据处理和数据可靠性

本文旨在阐明三元体系液-液平衡数据的实验测定和处理的一些概念和相关方面。溶解度曲线和双节线曲线之间有区别，设置由旋节线曲线定义的稳定性极限。此外，建议使用具有热力学基础的半经验模型进行平衡数据关联，而不是使用经验方程。此外，澄清了滥用这些经验方程（Hand、Bachman、Othmer-Tobias 等）作为数据质量或一致性的证明。
