Bodachivskyi, Iurii published the artcileUnderstanding the role of the substrate and the metal triflate acidic catalyst in sugar platform biorefineries: A comprehensive systematic approach to catalytic transformations of (poly)carbohydrates in ethanol, COA of Formula: C7H12O3, the main research area is levulinate furfural ethylacetal bronsted Lewis acid catalyst dehydration isomerization; polysaccharide dehydration bronsted acid catalyst preparation monosaccharide glucoside xyloside.
We systematically explore a range of model conversions of mono- and disaccharides, and of linear and branched polysaccharides under the catalytic action of metal trifluoromethanesulfonates (metal triflates) in ethanol. This highlights the preferred reactivity of specific (poly)carbohydrates, and the interplay between selectivities of the reactions and the dominating catalyst activity (Bronsted or Lewis). It unambiguously delineates that selectivities of acid-catalyzed transformations of (poly)carbohydrates into value added platform chems. rely on the origin of the substrate, any (pre)treatment, the acidic catalyst, and the reaction conditions. The optimized catalytic systems enable very efficient conversion of cellulosic carbohydrates into significantly value added Et glucosides (yields up to 63%), Et xylosides (yields up to 69%), Et levulinate (yields up to 75%), Et lactate (yields up to 98%), ethoxyacetaldehyde diethylacetal (yields up to 33%), and furfural diethylacetal (yields up to 44%), depending on the substrate and reaction conditions.
