Fast and continuous synthesis of 2,5-furandicarboxylic acid in a micropacked-bed reactor

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

“…Recently, a micropacked-bed reactor was developed and exploited to efficiently and rapidly produce FDCA over Au/CeO 2 catalyst in the presence of O 2 at 90 °C. 105 A high FDCA selectivity of 90% with complete conversion of HMF were obtained within 41 s, which is 1–2 orders of magnitude faster that of traditional reactors. This could be attributed to the enhanced gas–liquid mass transfer efficiency.…”

B-Containing Hydrotalcites Effectively Catalyzed Synthesis of 3-(Furan-2-yl)acrylonitrile Derivatives via the Knoevenagel Condensation

“…Crystals were grown in methanol using the slow evaporation method under normal atmospheric conditions at ambient temperature. The compound (3a) crystallizes in the monoclinic, P21/c, space group with cell parameters a (Å) = 4.9538 (8), b (Å) = 20.996 (2), c (Å) = 21.2982 (19), and β (°) = 91.521 (11) (Table S1).…”

“…HMF serves as an intermediate for producing different chemicals such as resins and polyester, , or it can be converted to 2,5-dimethylfuran (DMF), a liquid biofuel. , However, the low selectivity toward 5-(hydroxymethyl)­furfural leads to high production costs. Even the production of HMF is of limited output from cheap biomass sources since it requires tandem processes involving acidic and basic sites .…”

“…3,4 The Department of Energy identified a high-value-added furan compound 5 as one of the top ten valuable chemical platforms, which can be produced from the dehydration of carbohydrates such as fructose and glucose, among others. 6,7 HMF serves as an intermediate for producing different chemicals such as resins and polyester, 8,9 or it can be converted to 2,5-dimethylfuran (DMF), a liquid biofuel. 10,11 However, the low selectivity toward 5-(hydroxymethyl)furfural leads to high production costs.…”

Efficient and continuous furfural hydrogenation to furfuryl alcohol in a micropacked bed reactor

“…Recently, micropacked bed reactors (μPBRs), as a new type of continuous flow reactor, have been applied in biomass conversion processes, such as levulinic acid hydrogenation, 22 5-hydroxymethylfurfural oxidation, 23 and dehydration of glucose 24 due to their excellent gas–liquid–solid mass transfer characteristics. 25,26 Meanwhile, μPBRs are characterized by easy catalyst immobilization and recovery as well as better heat transfer performance.…”
