[en] This lecture illustrates our work in flow chemistry with bio-sourced platform molecules. Selected examples deal with the upgrading of biomass-derived small platform molecules, and in particular the implementation of a deoxydehydration (DODH) reaction of glycerol towards allyl alcohol under continuous-flow conditions. The combination of a unique reactive dynamic feed solution approach and short exposure time to high temperature gave high yield and excellent selectivity. Other polyols are also studied. The second part of the lecture illustrates our effort for the continuous-flow production of glycerol carbonate using low environmental footprint processes.
