Catalytic Oxidation of Furan and Hydrofuran Compounds. Part 7. Production of 2(5H)‐Furanone by Oxidation of Furfural with Hydrogen Peroxide and Some of Its Transformations in Aqueous Solutions.

Kinetics and modelling of furfural oxidation with hydrogen peroxide over a fibrous heterogeneous catalyst: effect of reaction parameters on yields of succinic acid

“…The influence of reaction temperature on the conversion of furfural, decomposition of hydrogen peroxide, formation and degradation of various products in the liquid phase and finally to carbon dioxide was thoroughly investigated. The temperature range (313–363 K) was taken from previous studies, while maintaining all the other parameters constant. Furfural converted slowly at 313 K, however, as expected the rate increased with temperature (Table ).…”

“…Another possibility to perform oxidation in the aqueous phase is to use hydrogen peroxide. The reaction can be carried out under the autocatalytic effect of acids, which are formed in the reaction mixture or in the presence of metal‐containing catalysts such as sodium molybdate, vanadium sulphate, vanadium pentoxide, sodium vanadate, vanadium, niobium, molybdenum, chromium salts, vanadyl sulphate‐sodium acetate system, niobium pentoxide, magnesium salts and titanium silicate . These metal‐containing catalysts provoke hydrogen peroxide decomposition and suffer from catalyst deactivation by leaching of the active metal.…”

Metal or Metal-Free Catalysis for the Oxidation of Biosourced Furfural

“…Simply by mixing furfural and hydrogen peroxide at 60−70 °C, with a molar ratio of 1 to 2 or 2.2, the same authors reported the formation of 2(5H)-furanone and succinic acid, each with a yield of 40%, and complete conversion of furfural. It is noteworthy that a high weight percentage of furfural, 16.1%, was employed, categorizing this transformation among those with the highest mass ratio 30,33 (Scheme 5, Table 2, entry 5). By changing the solvent, the product distribution is significantly altered.…”

Heterogeneous catalytic oxidation of furfural with hydrogen peroxide over a niobia catalyst

“…9 Numerous chemical and bio-routes exist to valorize furfural as a so-called bio-based platform molecule. Some of those methods reported in the literature 6 include hydrogenation, 10,11 aldol condensation, 12,13 amination, 14 oxidative esterification, 15 as well as gas- 16 and liquidphase [17][18][19] oxidations. Among these approaches, selective oxidation of furfural with hydrogen peroxide offers a promising pathway to various C4 chemical intermediates and products.…”
