文摘

Two types of metal鈥搊rganic frameworks (MOFs) have been synthesized and evaluated in the separation of C₂ and C₃ olefins and paraffins. Whereas Co₂(dhtp) (=Co鈥揅PO-27 = Co鈥揗OF-74) and Mg₂(dhtp) show an adsorption selectivity for the olefins ethene and propene over the paraffins ethane and propane, the zeolitic imidazolate framework ZIF-8 behaves in the opposite way and preferentially adsorbs the alkane. Consequently, in breakthrough experiments, the olefins or paraffins, respectively, can be separated.
