Furfural Oxidation with Hydrogen Peroxide Over ZSM-5 Based Micro-Mesoporous Aluminosilicates

Micro-mesoporous aluminosilicates based on ZSM-5 zeolite, obtained by a dual template method, as well as in the presence of a dual-functional template (i.e. a Gemini-type surfactant), were tested in the oxidation of furfural with hydrogen peroxide. Even substantial changes in acidity and porosity of the catalysts result in minor variations of selectivity towards the desired products. Application of the synthesized zeolite-based materials in the oxidation of furfural with hydrogen peroxide leads to formation of 2(5H)-furanone (yield up to 28.5%) and succinic acid (up to 19.5%) as the main C4 reaction products. The kinetic model developed previously to treat the results for oxidation of furfural over sulfated zirconia was able to describe the data also for micro-mesoporous aluminosilicates. [GRAPHICS] .

Automated summary

Micro-mesoporous aluminosilicates based on ZSM-5 zeolite were tested in the oxidation of furfural with hydrogen peroxide, showing minor variations in selectivity towards desired products despite substantial changes in catalyst acidity and porosity. The main C4 reaction products were 2(5H)-furanone and succinic acid, with yields up to 28.5% and 19.5% respectively. The kinetic model developed for sulfated zirconia oxidation of furfural was also able to describe the data for micro-mesoporous aluminosilicates.
