The Water Came with the Gas

Cycloaddition of Wet, Bore-Degassed CO₂ to Propylene Oxide over a Silica-Grafted Imidazolium Bromide in a Packed Bed

A paper from the School of Underlying Conditions and the School of Emergent Priorities feeds a packed bed of silica-grafted imidazolium bromide with carbon dioxide separated at an artesian monitoring bore, which arrives dilute and carrying entrained water in step with the bore's surges. A small water dose raised the propylene carbonate yield from 70% to 82% at 120 °C and a larger one hydrolysed product and stripped bromide from the bed, and a coalescer and buffer vessel that smoothed the water rather than removing it held the yield near 80% over 240 hours where the feed as received fell to 64%.
