“…The addition of more than 50 wt% of the catalyst resulted in a decline in the HMF yield for fructose dehydration reaction. This suggests that excessive PTSA-POM accelerated undesired HMF side reactions such as decomposition, condensation, and polymerization (Hu et al 2015).…”

“…After that, HMF yield, selectivity, and fructose conversion decreased slightly with increasing fructose loading. A high concentration of HMF generated with increased initial fructose loading led to an increase in undesired side reactions, such as self-polymerization of HMF or crosspolymerization between HMF and fructose (Hu et al 2015;Qi et al 2015), resulting in a poor HMF yield. The effect of the catalyst dosage (based on the weight of fructose) on the dehydration of fructose to HMF is shown in Table 2.…”

“…The different dehydration behaviors between glucose and fructose can be ascribed to their different structures. Glucose has a pyranosyl structure, which is much more stable than the furanosyl structure of fructose in the reaction medium (Hu et al 2015). Glucose must first be isomerized to fructose before transformation to HMF by Lewis acids such as metal chlorides or Sn-Beta.…”

“…Shen et al (2016) prepared a novel sulfonated bamboo-derived carbon (SBC) and discovered that the catalytic performance in the dehydration of fructose to HMF was excellent, and HMF yield reached 92.1% in THF/DMSO reaction medium. Hu et al (2015) described a magnetic ligninderived carbonaceous solid catalyst for HMF production in DMSO, and as high as 81.1% HMF yield was achieved at 130 °C in 40 min.…”

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 for the first time. The catalyst exhibited strong acidity, good water resistance, and high thermal stability. The present work focuses on the effects of various reaction parameters, including reaction temperature, time, water concentration, solvent, fructose level, and catalyst loading, on fructose dehydration. The catalyst exhibited excellent catalytic performance for HMF production from fructose in GVL and furnished a high HMF yield of 78.1% at 130 °C in 30 min. The recycling experiments suggested that the solid acid catalyst could be recycled at least seven times without a noticeable decrease in the catalytic activity. In addition, an attempt to study the one-step conversion of sucrose, glucose, and cellulose into HMF and furfural was performed using the same catalytic system.

The extraction/hydrolysis process of arabinoxylans from destarched wheat bran was studied in this work using different mesoporous silica supports and the corresponding RuCl3-based catalysts. The effects of temperature, time, catalyst supports and ruthenium catalysts were investigated and discussed in terms of the arabinoxylans extraction yield and their polymerization degree. Relatively high temperatures (180 ºC), short extraction times (10 minutes) and RuCl3 supported on Al-MCM-48 led to a high amount of arabinoxylans extracted (78%) with a low molecular weight (9 KDa). Finally, a relation between the operating conditions, the arabinoxylans extraction yield and the molecular weight was stablished based on the obtained results.

Millimeter size γ‐Al2O3 beads were prepared by alginate assisted sol–gel method and grafting organic groups with propyl sulfonic acid and alkyl groups as functionalized γ‐Al2O3 bead catalysts for fructose dehydration to 5‐hydroxymethylfurfural (5‐HMF). Experiment results showed that the porous structure of γ‐Al2O3 beads was favorable to the loading and dispersion of active components, and had an obvious effect on the properties of the catalyst. The lower calcination temperature of γ‐Al2O3 beads increased the specific surface area, the hydrophobicity and the activity of catalysts. Competition between the reaction of alkyl groups and ‐SH groups with surface hydroxyl during the preparation process of the catalyst influenced greatly the acid site densities, hydrophobic properties and activity of the catalyst. With an increase in the alkyl group chain, the hydrophobicity of catalysts increased obviously and the activity of the catalyst was enhanced. The most hydrophobic catalyst C16‐SO3H‐γ‐Al2O3–650°C exhibited the highest yield of 5‐HMF (84%) under the following reaction conditions: reaction medium of dimethylsulfoxide/H2O (V/V, 4:1), catalyst amount of 30 mg, temperature of 110°C and reaction time of 4 hr.
