Phys.org  September 18, 2024 Researchers in the UK explored the application of porous liquids for the separation of miscible liquids, using MEG/water (MEG=monoethylene glycol) and EtOH/water as proof-of-principle. PLs ZIF-8@PDMS (PL1, PDMS=polydimethylsilicone) or ZIF-8@sesame oil (PL2) each consisting of 25 wt % of the hydrophobic microporous material ZIF-8 was dispersed in PDMS or sesame oil respectively were physically stable to sedimentation. MEG was selectively extracted through a membrane from approximately into the PL phase. The PL could also be regenerated and re-used, suggesting its potential for continuous, cyclic extraction, PL3 (silicalite-1@PDMS) was effective in selective alcohol extraction from beverages. According to […]
