Selective upcycling of polyolefin waste has been hampered by the relatively high temperatures that are required to cleave carbon-carbon (C-C) bonds at reasonably rates. We present a distinctive approach uses highly ionic reaction environment increase polymer reactivity and lower energy transition states. Combining endothermic cleavage C-C with exothermic alkylation reactions cracking products enables full conversion polyethylene polypropylene liquid isoalkanes (C6 C10) below 100°C. Both...
Abstract Chloroaluminate ionic liquids selectively transform (waste) polyolefins into gasoline-range alkanes through tandem cracking-alkylation at temperatures below 100 °C. Further improvement of this process necessitates a deep understanding the nature catalytically active species and correlated performance in catalyzing critical reactions for polyolefin deconstruction with isoalkanes low temperatures. Here, we address requirement by determining nuclearity chloroaluminate ions their...
