For separating the special phenolic compound 2,6-xylenol from the model coal tar, the liquid–liquid equilibrium data regarding the four mixtures (toluene + 2,6-xylenol + glycerol/ethylene glycol/1,4-butanediol/1,3-propanediol) were measured at 303.15 K under pressure 0.1 MPa. The separation performance of the selected solvents was assessed by distribution coefficient (D) and separation factor (S). The experimental and calculated results showed that glycerol and ethylene glycol were suitable solvents. Meanwhile, the reliability of the measured data was checked by the Hand and Othmer–Tobias methods. In addition, the NRTL and UNIQUAC thermodynamic models were adopted to correlate the experimental data with the calculated values of root-mean-square deviation (RMSD) and absolute average relative deviation (AARD) lower than 0.01. The consistency of the regressed binary interaction parameters was verified using a tool GUI-MATLAB.

不同溶剂从芳香烃混合物中萃取2,6-二甲苯酚的三元液-液相平衡的测量和热力学模型

为了从模型煤焦油中分离特殊的酚类化合物2,6-二甲苯酚，需要对四种混合物（甲苯+ 2,6-二甲苯酚+甘油/乙二醇/ 1,4-丁二醇/ 1,3）进行液-液平衡数据-丙二醇）在303.15 K压力0.1 MPa下测量。所选溶剂的分离性能通过分布系数（D）和分离系数（S）。实验和计算结果表明，甘油和乙二醇是合适的溶剂。同时，通过Hand和Othmer-Tobias方法检查了测量数据的可靠性。此外，采用NRTL和UNIQUAC热力学模型将实验数据与均方根偏差（RMSD）和绝对平均相对偏差（AARD）的计算值相小于0.01。使用工具GUI-MATLAB验证了回归二进制交互参数的一致性。
