“…The peak located in 1700 cm −1 was attributed to carbonyl/carboxyl groups. The peak at around 1600 cm −1 could be corresponded to the stretching vibrations of aromatic‐like C=C in poly‐aromatic sketch . The vibration peaks at 1031 cm −1 , 1163 cm −1 , combined with peaks centered at 1006 cm −1 and 1398 cm −1 were identified, confirming the successful grafting of ‐SO 3 H groups onto the poly‐aromatic carbon structure …”

A carbonaceous solid acid catalyst obtained from by‐products of sorbitol dehydration process, was prepared via facile one‐step carbonization and sulfonation method. The results of various characterization technologies showed that as‐prepared acidic carbon bearing ‐SO3H, ‐COOH and ‐OH groups with Brønsted acid sites was effective for solvent‐free dehydration of sorbitol to produce isosorbide. Full complete sorbitol conversion with 72.1% isosorbide yield was achieved at 170 °C after 2 h reaction. Catalyst could be used for three cycles retaining the most of its initial catalytic activity. Importantly, the catalyst and reaction by‐products in this process could be easily recycled and facilely utilized, offering sustainable process in production of isosorbide from sorbitol.

“…1373 and 1580 cm −1 corresponding to the D and G bands, respectively . In general, the D band is ascribed to amorphous carbon due to carbon sheet stacking caused by incomplete carbonized catalyst structure . By contrast, the G band is assigned to the in‐plane sp 2 C−C stretching vibration (E 2g symmetry) of the crystalline graphite layers.…”

An Excellent Solid Acid Catalyst Derived from Microalgae Residue for Fructose Dehydration into 5‐Hydroxymethylfurural

et al. 2019

An environmentally benign carbonaceous solid acid was synthesized from microalgae residue discarded after biodiesel production. Thereafter, the as‐synthesized carbonaceous solid acid was used for catalytic dehydration of fructose into 5‐hydroxymethylfurural (5‐HMF). Various techniques such as X‐ray diffraction, N2 adsorption‐desorption, scanning electron microscopy, Fourier transform infrared, Raman, X‐ray photoelectron spectroscopy and pyridine adsorption etc were conducted to elucidate the structural and acidic properties of the solid acid so as to build the structure‐performance relationship. The results suggested that large amounts of ‐SO3H, phenolic ‐OH and ‐COOH groups were grafted onto the investigated material and most of the surface acid sites were assigned to strong Brönsted acid sites. In screening tests with other commercial catalysts, the as‐prepared sample presented excellent catalytic activity with 76.65±2.53% yield of 5‐HMF under aqueous conditions. The dehydration of fructose in dimethyl sulfoxide‐water biphasic system was also tested, affording the 5‐HMF yield as high as 93.84±1.12%. This work provides an efficient and selective solid acid from biodiesel waste and might shed light on an alternative catalyst for highly efficient production of 5‐HMF instead of homogeneous catalysts.

A water‐soluble, cyclodextrin‐supported palladium complex (DACH‐Pd‐β‐CD) catalytic system was designed and synthesized, which can efficiently catalyze Suzuki–Miyaura cross‐coupling reactions between aryl halides and arylboronic acid in water under mild conditions. The catalyst was successfully characterized using the methods of transmission electron microscopy, energy‐dispersive X‐ray spectrometry, X‐ray diffraction, thermogravimetric analysis, and Fourier transform infrared and NMR spectroscopies. Furthermore, the catalyst can be easily separated from the reaction mixture and still maintain high catalytic activity after ten cycles. No leaching of palladium into the reaction solution occurred. The advantages of green solvent (water), short reaction times (2–6 h), low catalyst loading (0.001 mol%), excellent yields (up to 99%) and reusability of the catalyst mean it will have potential applications in green chemical synthesis.
