The separation of chlorobenzene () and chlorocyclohexane () using traditional industrial separation technologies (distillation, fractionation, and rectification) is a great challenge due to their close boiling points. Here, we report an innovative method for the separation of the mixture of and by nonporous adaptive crystals (NACs) of perethylated pillar[6]arene (). NACs of () can selectively adsorb vapor from the vapor mixture of and (: = 1:1) with a purity of 99.5%. Furthermore, can be recycled for five times without a significant loss of performance.

由于氯苯（）和氯代环己烷（）的沸点相近，采用传统工业分离技术（蒸馏、分馏和精馏）分离它们具有很大挑战。在此，我们报道了一种通过全乙基化柱[6]芳烃（）的无孔自适应晶体（NACs）分离和混合物的创新方法。（）的NACs能够从和（体积比 = 1:1）的蒸汽混合物中选择性吸附蒸汽，纯度可达99.5%。此外，可以循环使用五次而性能无显著损失。
