Continuous Flow For Biomass-based Chemicals Production

Christophe Len, Professor, Université de Technologie de Compiègne

The principles of sustainable development, the bio-economy, and the circular economy are increasingly being applied to the synthesis of industrially relevant molecules. In this context, furfural and glycerol, which serve as platform molecules, are the subject of diverse research approaches aimed at improving their conversion into valuable compounds. Given the current momentum in promoting green chemistry for sustainable development, chemists have recently pioneered catalytic reactions utilizing innovative technologies, such as continuous flow processes. This study highlights recent advancements in the continuous production of derivatives obtained from furfural and glycerol. Among the noteworthy molecules of interest are furfuryl alcohol, levulinic acid and its esters, gamma valerolactone, acrolein, quinoline-type derivatives, solketal, triacetin, and glycerol oligomers. These derivatives are synthesized from biomass or carbohydrates, utilizing both homogeneous and heterogeneous catalysts. Various reaction parameters, including temperature, catalyst and feedstock loadings, and solvent types, have been meticulously fine-tuned with a focus on time efficiency. The conceptualization, synthesis, and detailed examination of the physicochemical properties of these derivatives will be comprehensively addressed.
