Liquid–liquid equilibrium (LLE) data for the ternary mixture of water + 2,2,3,3-tetrafluoro-1-propanol (TFP) + {1-pentanol or 2-ethyl-1-hexanol or n-propyl acetate or dichloromethane} was measured in 101.3 KPa and 303.2 K. The distribution coefficient and separation factor appraised utility for extracting TFP from water. The experimental LLE data were related by the nonrandom two liquid and universal quasichemical models for which the absolute average deviation and root means square deviation were no more than 0.0029 and 0.0035, respectively.

水，2,2,3,3-四氟-1-丙醇和不同溶剂的三元体系的液-液平衡数据和热力学模型

水+ 2,2,3,3-四氟-1-丙醇（TFP）+ {1-戊醇或2-乙基-1-己醇或乙酸正丙酯或在101.3 KPa和303.2 K下测量二氯甲烷}。分配系数和分离因子评估了从水中提取TFP的效用。LLE实验数据与非随机两种液体和通用拟化学模型相关，其绝对平均偏差和均方根偏差分别不超过0.0029和0.0035。
