Bis-sulfonic acid ionic liquids for the conversion of fructose to 5-hydroxymethyl-2-furfural.
Homogenous bis-sulfonic acid ionic liquids (1 mol equiv.) in DMSO (10 mol equiv.) at 100 °C efficiently mediated the conversion of D-fructose into 5-hydroxymethyl-2-furfural in 75% isolated yield, which was roughly a 10% increment compared to the case of the mono-sulfonic acid ionic liquids.
متن کاملConversion of fructose into 5-(hydroxymethyl)furfural in sulfolane.
Population growth has created an expanding gap between the supply and demand of both energy and chemicals. Nonrenewable fossil sources, such as coal, natural gas, and petroleum, are the source of nearly 86% of the world’s energy and 96% of its organic chemicals. Diminishing reserves of these sources, rising atmospheric CO2 levels, and socioeconomic concerns require a reduction of our dependence...
متن کاملChemicals from Biomass: Aerobic oxidation of 5-hydroxymethyl-2-furaldehyde into diformylfurane catalyzed by immobilized vanadyl-pyridine complexes
Introduction 5-Hydroxymethyl-2-furaldehyde (HMF), as diformylfurane precursor (DFF), is obtained from fructose or glucose dehydration. DFF is a versatile chemical, and there are numerous reports describing various applications as a monomer, as starting materials for the synthesis of pharmaceuticals and antifungal agents [1]. To date, few reports describe the use of air to oxidize (HMF) with het...

The purpose of this study was to develop a sensitive and fast microdialysis coupled with high-performance liquid chromatographic (HPLC) method for determination of 5-hydroxymethyl-2-furaldehyde (5-HMF) in free-moving rats after i.g. administration of the aqueous extract of crud Fructus corni and its processed products of jiuzheng pin (JZP). The concentration of 5-HMF in free-movi...
