A biphasic system including acidic lithium bromide trihydrate effectively converted lignocellulosic biomass into bromomethylfurfural (BMF), furfural (FF) and depolymerized lignin.
Cleavage of aryl ether (Caryl-O) bonds is crucial for conversion and value-added utilization of lignin and its derivatives, but remains extremely challenging under mild conditions due to strong Caryl-O linkages....
33.6% fructose and 52.1% HMF were achieved from glucose isomerization and dehydration in CaCl2 salt hydrate. Interactions existing in β-glucopyranose-CaCl2 and β-d-fructofuranose-Ca2+ promoted the glucose isomerization and fructose dehydration.
The side reactions of saccharides and 5-hydromethyl furfural to form humins were suppressed by controlling the cellulose hydrolysis reaction to match the subsequent reactions.
Developed as energy-efficient and integrated method for soluble sugars and furfurals with high yields and high carbon efficiency from polysaccharides and lignocellulosic biomass.
