Sun, Yingnan published the artcileIn Situ Approach to Dendritic Fibrous Nitrogen-Doped Carbon Nanospheres Functionalized by Bronsted Acidic Ionic Liquid and Their Excellent Esterification Catalytic Performance, Safety of Benzyl acetate, the main research area is bronsted acidic ionic liquid dendritic fibrous nanocarbon esterification.
Chem. bonding of Bronsted acidic ionic liquids (BAILs) on suitable supports is one of the promising strategies to develop efficient solid acids for catalytic conversion of biomass/derivatives to fuels and value-added chems. For this purpose, a series of dendritic fibrous nitrogen-doped carbon nanospheres functionalized by BAILs are demonstrated for the first time via an in situ silica nanocasting approach followed by chem. modification with 1,3-propanesultone and trifluoromethanesulonic acid successively. The resulting DFNC-[C3N][OTf] (C3 = PrSO3H, OTf = SO3CF3) serve as the solid acid catalysts for three biomass conversion-concerned esterification reactions, and by the combination of the advantages of superstrong Bronsted acidity, fascinating dendritic fibrous nanostructures, and interesting hierarchical micro-mesoporosity, the DFNC-[C3N][OTf] catalysts exhibit excellent esterification activity. More importantly, the cooperation of chem. bonding the -[C3][OTf-] sites on the dendritic fibrous nitrogen-doped carbon (DFNC) support and stabilizing the -[C3][OTf-] sites within the wrinkled fibers of the support result in the DFNC-[C3N][OTf] catalysts’ excellent reusability, and they can be reused at least five times without obvious changes in catalytic activity, nanostructures, porosity properties, and Bronsted acidity.
ACS Sustainable Chemistry & Engineering published new progress about Bronsted acids Role: CAT (Catalyst Use), PRP (Properties), USES (Uses). 140-11-4 belongs to class esters-buliding-blocks, name is Benzyl acetate, and the molecular formula is C9H10O2, Safety of Benzyl acetate.
