Abstract

original image

A breakthrough result: The microporous metal–organic framework MIL-47 is an excellent adsorbent for the separation of C8 alkylaromatic compounds, such as ethylbenzene, meta-xylene, and para-xylene. The potential of MIL-47, with its high uptake capacity and its hydrophobic nature, for real separations of the C8 alkylaromatic compounds was demonstrated by breakthrough and chromatographic experiments (see picture).
