“…To ascertain the contribution of HPO 4 2− for the isomerization of glucose, the assistant effect of HPO 4 2− on H 2 PO 4 — for glucose isomerization was investigated (Figure ). The results demonstrated that in the presence of additional HPO 4 2− , the isomerization efficiency of glucose improved markedly, implying HPO 4 2− did promote (catalyze) the isomerization of glucose into fructose ,. Furthermore, the minor contribution from H + in H 2 PO 4 — catalyzed systems for glucose isomerization has also been confirmed seriously through the controlled experiments (Figure S5, Supporting information).…”

An eco‐friendly catalytic system consisted of dihydric phosphate (H2PO4—) catalyst and a methyl isobutyl ketone (MIBK)/H2O biphasic solvent has been constructed to produce 5‐hydroxymethylfurfural (HMF) from sucrose, a cheaper and more widely available feedstock than fructose. The effects of reaction conditions, viz., catalyst dosage, reaction temperature, and reaction time, on this dehydration reaction have been investigated systematically, affording more than 70% of HMF yield under the optimum conditions. This environmentally friendly system is also broadly substrate‐tolerant, high concentration of sucrose (86%), scalable catalytic system (scaled up 10 times), and sugarcane juice also give 62.5%, 70.1%, and 70.7% of HMF yield, respectively. Moreover, the function of H2PO4— containing system for isomerization of glucose into fructose has been confirmed; and the dehydration reaction has been proposed to proceed through the catalytic hydrolysis of sucrose into glucose and fructose by protons (H+), followed by the isomerization of glucose into fructose by hydrogen phosphate ions (HPO42−), and the dehydration of fructose into HMF by protons (H+), which are all from the dissociation of H2PO4— ions. Readily available and eco‐friendly catalyst, abundantly available feedstock, and simple reaction conditions could mark this process promising for HMF production in industry.

“…The ionic liquid and catalyst showed no decrease in activity after being recycled three times. Lu et al used an acidic phosphate buffer system to convert concentrated solutions of fructose and glucose (up to 50 wt%) to HMF, with a conversion of over 85% and HMF yield of more than 62% being obtained in case of fructose [294]. Conversions and yields for glucose were much lower, but when borate was added as a promoter to increase isomerisation of glucose to fructose, a conversion of 87% and yield of 43% was obtained for a 30 wt% solution.…”

“…The yield of LA (4.24% or 40 mg.g -1 dry biomass) was achieved by decomposing the HMF and rehydrating it in the aqueous medium of the hydrolysate, which explains the low yield of HMF (Liu et al, 2020). Lu et al (2012) obtained 7% yield of LA and 4% of HMF from glucose using phosphoric acid in a phosphate buffer system under microwave radiation. Scapin et al (2020) achieved yields of 65%, 23.7% and 3% of FF, LA and HMF, respectively, in the pequi shell hydrolysate reaction with [BMIM][Br].…”

Lignocellulosic waste is a valuable source of energy, fuels, and raw materials for the chemical industry. In this study, the potential of cupuaçu husks, derivative from a typical fruit of the Brazilian Amazon, was evaluated. Therefore, biomass was submitted to acid hydrolysis and pyrolysis, and the contents of sugars, by-products, bio-oil compounds, and bio-oil theoretical energy potential were determined. X-ray diffraction, High performance liquid chromatography, Fourier-transform infrared and Gas chromatography mass spectrometry analyzes were used. The hydrolysate has considerable sugar levels (31.7%) and presence of relevant by-products including furfural, levulinic acid and hydroxymethylfurfural. Bio-oil contained a variety of phenolic compounds, and its theoretical energy potential suggested usability of cupuaçu husks for energy generation. Economic analysis showed that commercialization of bioproducts obtained by biomass hydrolysis and pyrolysis could be highly profitable. These outcomes indicate a range of applications for cupuaçu husks in biorefinery processes and potential to promote sustainability and social development.
