Guo, Haixin published the artcileSynthesis of ethyl levulinate over amino-sulfonated functional carbon materials, Formula: C7H12O3, the main research area is ethyl levulinate preparation amino sulfonated functional carbon catalyst.
Functional carbon materials (FCM) containing amino and sulfonate groups (NS-FCM) were prepared with one-pot hydrothermal carbonization of cellulose using ammonium formate and 5-sulfosalicylic acid additives. The catalytic materials were applied to levulinic acid or furfuryl alc. substrates in ethanol solvent for synthesizing Et levulinate (EL). Catalytic activity of NS-FCM was found to be related to its sulfonate groups, while substrate selectivity of NS-FCM was found to be related to its amino groups as supported by equilibrium adsorption and reaction experiments Pre-adsorbed LA substrate onto NS-FCM followed by ethanol treatment at reaction conditions achieved EL yields higher than 90% that is attributed to a selective adsorption and cooperative desorption mechanism. The activity of NS-FCM catalyst was stable for five reuse cycles, but lost about 10% of its activity from the third cycle that is attributed to adsorption of humin precursors onto active sites.
Renewable Energy published new progress about Acidity. 539-88-8 belongs to class esters-buliding-blocks, name is Ethyl 4-oxopentanoate, and the molecular formula is C7H12O3, Formula: C7H12O3.
