烯烃/链烷烃混合物的分离对于石油化工工业是非常重要的，主要通过使用能量密集型低温蒸馏来实现。本文报道了一种具有温敏性开门行为的柔性柱撑结构CPL-1对C3 H6的吸附。测定了CPL-1在273、278、283、288、293和298 K六个温度下的C3 H6和C3 H8吸附和脱附等温线。结果表明，在273 ~ 288 K范围内，CPL-1吸附C3 H6的开阀压力随吸附温度的升高而增大。然而，在测量的压力范围内没有观察到闸门打开效应（
The separation of olefin/paraffin mixtures is of great importance for the petrochemical industry, mainly achieved by using energy-intensive cryogenic distillation. We herein reported a flexible pillared-layer framework CPL-1 possessing a thermoresponsive gate opening behavior for C3H6 adsorption. We measured the C3H6 and C3H8 adsorption and desorption isotherms of CPL-1 at six different temperatures (273, 278, 283, 288, 293 and 298 K), respectively. Results showed that the gate opening pressure of C3H6 adsorption for CPL-1 increased with an increase of the adsorption temperature from 273 K to 288 K. However, no gate opening effect was observed within the measured pressure (
