Liu, Chenlu published the artcileEsterification of levulinic acid into ethyl levulinate catalyzed by sulfonated bagasse-carbonized solid acid, Related Products of esters-buliding-blocks, the main research area is levulinic acid esterification ethyl levulinate sugarcane bagasse sulfonated carbon.
A sulfonic carbon-based catalyst (C-SO3H) was successfully prepared by sulfonating incompletely carbonized sugarcane bagasse. The optimized catalyst of high activity in the esterification of levulinic acid (LA) with ethanol was produced under sulfonation at 150 °C for 15 h with a 75 mL/g sulfonation ratio. The prepared catalysts were characterized by X-ray powder diffraction (XRD), Fourier transform IR (FTIR) anal., SEM (SEM), and elemental anal. (EA). The bagasse-carbonized catalyst was porous, and the porous structure remained unchanged after sulfonation treatment. Moreover, the introduced acidic group was the catalytic center. A high yield of Et levulinate (ELA) of 88.2% was obtained at 120 °C for 9 h. The sulfonic carbon-based catalyst could be reused at least five times and still exhibited great stability. The application of the sulfonic carbon-based catalyst was not only the effective use of biomass resources but also promoted the production of various high value chems.
