Various metal-organic frameworks (MOFs) were prepared and used as a column packing for chromatographic separation of para-xylene. With MOFs prepared with large linker molecules, xylenes diffused into the micropores and eluted fundamentally according to the kinetic molecular size. With MOFs of very small micropore, xylenes passed spaces between MOF particles. With MOF composed of fumaric acid and Zr4+, ortho- and meta-xylenes eluted quickly and para-xylene was separated by the molecular-sieving mechanism.
