Catalytic upgrading of biomass into various alkyl levulinates has gained wide attention recently. Particularly, Et levulinate (EL) shows great potential as gasoline additive and substitute of biodiesel fuels. Hypercrosslinked organic polymer based carbonaceous materials with large surface areas and strong Bronsted acidity were synthesized and developed as highly efficient solid acids for the direct transformation of biomass derived carbohydrates into biofuel candidate Et levulinate (EL). Controllable Brunauer-Emmett-Teller (BET) surface area and proper acid d. of as-prepared carbonaceous materials were demonstrated to be crucial for the successful synthesis of EL. Among the catalysts, α,α’-dichloro-p-xylene derived hypercrosslinked organic carbocatalyst (HDS-3.6) exhibited the best results for EL formation with the optimal yield of 70.3% at a temperature of 423 K, which was comparable with those of frequently-used solid acids such as com. Amberlyst-15 and metal oxides. The presence of DMSO (DMSO) in the catalytic system facilitated the production of intermediates 5-hydroxymethylfurfural (HMF) and 5-ethoxymethylfurfural. Notably, the hypercrosslinked organic polymers with abundant Bronsted acid sites were much more effective in the catalytic synthesis of levulinate esters from ketoses. The prepared hypercrosslinked organic polymers were efficient and robust catalysts to produce various biomass derived alkyl levulinates with high activity and stability.
Journal of Chemical Technology and Biotechnology published new progress about Bronsted acidity. 539-88-8 belongs to class esters-buliding-blocks, name is Ethyl 4-oxopentanoate, and the molecular formula is C7H12O3, Product Details of C7H12O3.
