采用离子液体支撑液膜分离甲苯/环己烷。采用量子化学计算和液-液萃取过程对离子液体与甲苯和环己烷的相互作用进行了计算和实验研究。结果表明，[BPy][BF_4]与甲苯的相互作用强于与环己烷的相互作用。在温度为323 K，流速为13.5 mL·min-1时，壳侧和腔侧的选择性均大于10。由于IL的粘度较高，SILM工艺具有良好的长期稳定性。由于SILM过程中传质驱动力的作用，随着甲苯初始浓度的增加，膜通量和去除效率增加，但由于竞争性传质，选择性降低。根据阻力串联模型和实验结果，传质阻力主要是层液膜相。流速对两侧的影响很小。较高的温度可以显著提高传质性能。随着操作温度从298 K升高到323 K，去除率从28.2%增加到45.1%。
A supported liquid membrane with ionic liquid was used for the separation of toluene/cyclohexane. The interactions of ionic liquid with toluene and cyclohexane were calculated and experimentally studied by quantum chemical calculation and liquid-liquid extraction process. The results showed [BPy][BF4] have stronger interaction with toluene than that with cyclohexane. The selectivity of SILM processes was larger than 10 at the temperature of 323 K and the flow rate of 13.5 mL·min−1on both shell side and lumen side. Due to the higher viscosity of IL, SILM process had good long-term stability. As the effects of mass transfer driving force of SILM process, the flux and removal efficiency increased with increase of initial toluene concentration, while the selectivity decreased because of the competitive transport. Base on the resistance in-series model and experimental results, the mass transfer resistance was mainly lay liquid membrane phase. The influence of flow rates on both sides was slight. The higher temperature could enhance the mass transfer performance significantly. The removal efficiency increased from 28.2% to 45.1% with the increasing of operation temperature from 298 K to 323 K.
