Chemical transformations of 5-hydroxymethylfurfural into highly added value products: present and future

Abstract

The synthesis of fuels, fuel additives, commercial and potential products from the platform molecules generated by the hydrolysis of the lignocellulosic biomass is a promising strategy toward the utilization of...

An unconventional iron oxide catalyst for 5-hydroxymethylfurfural oxidation to 2,5-diformylfuran

“…However, unfortunately, the applied reaction parameters resulted in the desired product DFF with a significant decrease in conversion and selectivity by 18 and 5%, respectively (Table 1, entry 13). Furthermore, to increase the polarity of reaction media, we also examined some other moderate polar cyclic and acyclic ethers as solvents but these media afforded comparatively moderate 5-HMF conversions (Table 1, entries [14][15][16]. Then, to study further the impact of highly polar and protic reaction…”

“…13 Electrocatalysis is another sustainable tool, which is recently being utilized for biomass upgradation to furan-based fine chemicals via oxidation reactions. 14,15 For this, mostly Ni, Co, Mn and Pt metal-based catalysts with rich oxygen vacancies have been investigated.…”

The functional and synergetic optimization of the thermal-catalytic system for the selective oxidation of 5-hydroxymethylfurfural to 2,5-diformylfuran: a review

“…However, the low optimal dosage of HMF under these two catalytic systems limits the large-scale production of DFF. [24][25][26][27][28] In contrast, the thermal catalytic system exhibits faster reaction rates at the optimal substrate dosage. Although excessive oxidation of the hydroxyl functional groups can easily occur at high temperatures, which also can be avoided by modifying the catalyst or optimizing the reaction conditions such as reaction temperature and oxygen pressure.…”

Oxygen Vacancy-Induced Metal–Support Interactions in AuPd/ZrO2 Catalysts for Boosting 5-Hydroxymethylfurfural Oxidation

“…1,2 HMF is equipped with a furan ring and C�O, C−O, C�C, −OH groups, which make it a key platform compound for a variety of high value-added fine chemicals, biofuels, and biodegradable polymers. 3,4 For example, further upgrading and catalytic oxidation of both aldehyde and hydroxymethyl functional groups of HMF can produce 2,5-furandicarboxylic acid (FDCA), which is identified as one of the Top 12 biobased building blocks by the U.S. Department of Energy. 5 FDCA has a rigid aromatic diacid structure and represents a great potential as an alternative for the petroleum-derived terephthalic acid (TPA) derived from fossil resources.…”
