In the study, the mole fraction solubility of bifenthrin in pure solvents (methanol, ethanol, isopropanol, and cyclohexane) and binary solvents (methanol + ethanol, methanol + isopropanol and ethanol + isopropanol) at atmospheric pressure from T = (293.15 to 328.15) K was measured via a gravimetric method. The results show that the solubility of bifenthrin in the selected solvents increased with the increasing of temperature, and the solubility in cyclohexane was relatively maximum. In addition, the solubility data were correlated with using the modified Apelblat equation, the λh equation, the NRTL model, the Sun model and the newly proposed Apelblat-Sun model. In addition, the calculation of dissolution thermodynamics by using Van't Hoff equation showed that the mixing process of bifenthrin in the selected solvents were all endothermic and entropy-driven processes. The experimental results provided help for the separation and purification of bifenthrin.

在这项研究中，联苯菊酯在大气压下在纯溶剂（甲醇，乙醇，异丙醇和环己烷）和二元溶剂（甲醇+乙醇，甲醇+异丙醇和乙醇+异丙醇）中的摩尔分数溶解度为T =（293.15至328.15） K通过重量分析法测量。结果表明，联苯菊酯在所选溶剂中的溶解度随温度的升高而增加，在环己烷中的溶解度相对最大。此外，使用改进的Apelblat方程，λh方程，NRTL模型，Sun模型和新提出的Apelblat-Sun模型，将溶解度数据与相关。此外，使用Van'计算溶出热力学 t Hoff方程表明联苯菊酯在所选溶剂中的混合过程都是吸热和熵驱动的过程。实验结果为联苯菊酯的分离和纯化提供了帮助。
