“…However, the transformation of glucose to HMF is more difficult than the fructose route and requires two steps. First, glucose is isomerized to fructose over the basic or Lewis acid catalysts; second, fructose was dehydrated to HMF in the presence of the Brønsted acid catalysts. , This means that two functions of catalysts are simultaneously needed for direct conversion of glucose to HMF . In this regard, one-pot catalytic systems that combine the dual functionality of acid and base groups have gained widening attention in recent years. , …”

The one-pot synthesis of 5-hydroxymethylfurfural (HMF) from glucose as a cheap feedstock under mild conditions continues to be challenging for the chemical industry. Herein, a solid acid–base bifunctional catalyst was prepared by the postsynthetic modification of MCM-41 mesoporous silica with 3-chloropropyltriethoxysilane and subsequent anchoring of sulfanilic acid to its surface. A combination of N2 sorption, X-ray diffraction, and transmission electron microscopy studies proved that the ordered mesostructure of MCM-41 was preserved during the process of catalyst preparation. The as-synthesized catalyst was successful in the one-pot production of HMF from glucose in an aqueous medium. The influences of numerous reaction parameters on the HMF yield were examined in detail. In optimal circumstances, 89% HMF was obtained by glucose conversion at 100 °C and 120 min using 20 mg of catalyst. Remarkably, the catalyst was tested up to six recycles and demonstrated no observable drop in catalytic performance, indicating its potential for industry applications.

“…HMF is an integral part of biofuel chemistry and the petrochemical industry, and typically has been produced through the acid-catalyzed hydration of monosaccharides 8 . In recent times, more focus has been placed on developing HMF from renewable biomass-based sugars 9 . Disaccharides or polysaccharides, such as sucrose, cellobiose, inulin, or cellulose can also be employed as sources of HMF, but they require a hydrolysis process to break down into their individual components before dehydration to HMF 10 .…”

A novel bio-based nanocomposite was designed based on modification of halloysite with k-carrageenan viaprecipitation polymerization with acrylic acid in aqueous media. Various analyses were conducted to verify the formation of the catalyst. Afterwards, it was tested as a solid acid catalyst for the dehydration of fructose, resulting in the production of 5-hydroxymethylfurfural. Effective parameters, such as catalyst amount, temperature, and the reaction time were optimized and it was revealed that 10 wt% catalyst at 100 °C gave the desired product in 97.9% yield in 35 min. The catalyst was also reusable and could be reused up to four runs. Comparison of the activity of the catalyst with halloysite and k-carrageenan confirmed superior activity of the former, which was attributed to its higher acidity and possible synergism between the components. Moreover, the composite with lower content of the polymeric moiety was less effective, approving the role of the conjugated polymeric part in the catalytic activity. Thus, the present protocol would open up an innovative opportunity for the preparation of a bio-based catalytic system from naturally occurring components. In fact, k-carrageenan as a carbohydrate containing acidic functionality in its backbone was successfully applied for improving the acidity of the nanocomposite.
