High Efficiency Catalytic Transfer Hydrogenation of Furfural to Furfuryl Alcohol Over Metallic Oxide Catalyst

One-Pot Conversion of Furfural to Gamma-Valerolactone over Zr-SBA-15: Cooperation of Lewis and Brønsted Acidic Sites

“…This is because the LAS of ZrO 2 favors the CTH reaction of FUR to FAL, and FAL hardly converts to IPL due to the lack of BAS of ZrO 2 ; the result was consistent with our recent report. 4,21 To our surprise, the selectivity of GVL and IPL increased to 25.7 and 65.1%, respectively (entry 3), when a small amount of zirconium was incorporated into the SBA-15 (Si/Zr = 730), suggesting that zirconium is not only supported on the surface of SBA-15 in the form of ZrO 2 but also enters into the framework of SBA-15 to form a small amount of BAS (Figure 2b). Further increasing the amount of zirconium, i.e., decreasing the molar ratio of Si/Zr to 25 (entries 3−8), the GVL selectivity increased to 93.3% and IPL selectivity decreased to 2.9%, and the selectivity of FAL was almost unchanged (1.2−4.1%).…”

“…The H-donor or solvent is known to play an important role in the CTH reaction, ,,− and the one-pot conversion of FUR to GVL involves two CTH reactions. We also investigate the H-donor effects on the catalytic performance of Zr-SBA-15 at 190 °C.…”

“…Research on the catalytic conversion of biomass platform compounds into value-added products has rapidly expanded due to the depletion of fossil fuels and the deterioration of the environment. , Furfural (FUR) as an abundant and low-cost biomass platform molecule can be easily produced by dehydration of corncobs or other lignocellulosic biomass . FUR could be transformed into many value-added compounds through hydrogenation, , oxidation-condensation, − oxidative esterification and ring opening reaction, and so on. γ-Valerolactone (GVL), as one of the products of FUR, has attracted extensive attention due to its excellent physical and chemical properties.…”

Design of Heterogeneous Catalysts for the Conversion of Furfural to C5 Derivatives: A Brief Review

“…A study using pyridine-poisoned catalysts revealed that the conversion rate dropped from 87.1 to 44.3%, reinforcing the importance of acidic sites. Liu et al [26] synthesized metallic oxides (MgO, ZrO 2 , Fe 2 O 3 , and Al 2 O 3 ) containing acidic and basic sites following the precipitation method to realize the hydrogenation of FF to FA following the catalytic hydrogen transfer method using different alcohols as the hydrogen source. The maximum extent of FF conversion and FA yield was achieved using 2-propanol, and this could be attributed to the low reduction potential and the low steric effect recorded for 2-propanol (compared to the other alcohols with a higher carbon chain).…”

Hydrogenation of BHMF with controllable selectivity to tetrahydropyranone and 1-hydroxy-2,5-hexanedione under atmospheric H2pressure

“…[21][22][23][24] For example, methyl furan 25 or 2,5dimethylfuran [26][27][28] could be used as fuel additives. Furfuryl alcohol 21,[29][30][31][32][33] and tetrahydro-2,5-furandimethanol 34 could be used as polymer monomers. Traditionally, the furan structure of the biomass-derived furans often remained intact during the hydrogenation process.…”
