Catalytic conversion of carbohydrates into 5-hydroxymethylfurfural by germanium(IV) chloride in ionic liquids.
Direct conversion of carbohydrates into 5-hydroxymethylfurfural (HMF) catalyzed by germanium(IV) chloride in ionic liquids has been investigated in search of an efficient and environmentally friendly process. Monosaccharides D-fructose and D-glucose, disaccharides sucrose and maltose, and even the polysaccharide cellulose were successfully converted into HMF with good yields under mild conditio...
متن کاملConversion of fructose into 5-hydroxymethylfurfural (HMF) and its derivatives promoted by inorganic salt in alcohol.
The conversion of D-fructose to 5-hydroxymethylfurfural (HMF) on a 1 mmol scale was achieved in good yield (68%) using NH(4)Cl as catalyst in isopropanol at 120°C. About 3% of 5-i-propoxymethylfurfural was formed. The reaction in ethanol at 100°C on a 10g scale gave a total yield of HMF and 5-ethoxymethylfurfural of 42%. No mineral acid such as H(2)SO(4) and HCl are required.
متن کاملCaprolactam from renewable resources: catalytic conversion of 5-hydroxymethylfurfural into caprolactone.
Lignocellulosic biomass is a very promising feedstock for the production of biobased chemicals. The C6 sugars (for example d-glucose, d-fructose, and d-mannose) in lignocellulosic biomass are interesting precursors for a broad range of chemicals with high application potential. Apart from fermentation to bioethanol and reforming to CO/H2, [10] the direct conversion of these sugars to useful pla...
متن کاملA Facile and Eco-Effective Catalytic System for Synthesis of 5-Hydroxymethylfurfural from Glucose
A facile and eco-friendly system for synthesis of 5-hydroxymethylfurfural (HMF) from glucose has been investigated with the catalyst dihydric phosphate (H2PO4) in a methyl isobutyl ketone (MIBK)/H2O biphasic system. The results showed that the catalyst dosage, reaction temperature, and reaction time had noticeable effects on glucose conversion and the HMF yield; more than 50% yield of HMF was a...
متن کاملCatalytic Conversion of Biomass-derived Carbohydrates into 5-Hydroxymethylfurfural using a Strong Solid Acid Catalyst in Aqueous γ-Valerolactone
Selective conversion of biomass-derived carbohydrates into 5-hydroxymethylfurfural (HMF) is of great significance for biomass conversion. In this study, a novel solid Brønsted acid was prepared simply by the copolymerization of paraformaldehyde and p-toluenesulfonic acid and then used to catalyze the conversion of various carbohydrates into HMF in γ-valerolactone-water (GVL/H2O) reaction medium...
