Adsorptive separation of alkane isomers, especially the efficient separation of mono- and dibranched alkanes, remains challenging in the petrochemical industry. We report here the discrimination of alkane isomers through a thermodynamically driven mechanism by a highly stable calcium-based metal-organic framework. This newly developed 3D structure is built on a tetracarboxylate linker, featuring 1D channels with optimal pore dimensions to discriminate alkane isomers.
烷烃异构体的吸附分离，尤其是单支链和双支链烷烃的高效分离，在石化行业中仍然具有挑战性。我们在此报告通过一种高度稳定的钙基金属有机框架，基于热力学驱动机制对烷烃异构体进行区分。这种新开发的三维结构基于一种四羧酸连接体构建而成，具有一维通道，其孔径尺寸最佳，可用于区分烷烃异构体。
