Efficient Solid Acid Catalyst for the Production of Furfurals

Brønsted and Lewis acidic sulfonated carbonaceous catalyst ( http://bit.ly/1jYjScU)

Self-assembled nanoparticulates of porous sulfonated carbonaceous TiO2 material that contain Brønsted and Lewis acidic sites were prepared by a one-pot synthesis method. The carbonaceous heterogeneous catalyst (Glu-TsOH-Ti) with a Brønsted-to-Lewis acid density ratio of 1.2 and more accessible acid sites was effective to produce 5-hydroxymethylfurfural and furfural from biomass-derived mono- and disaccharides and xylose in a biphasic solvent that comprised water and biorenewable methyltetrahydrofuran ..

DalinYebo‘s insight:

HMF can be converted to 2,5-dimethylfuran (DMF), which is a liquid biofuel with a greater energy content bioethanol. Oxidation of HMF gives 2,5-furandicarboxylic acid, which has been proposed as a replacement for terephthalic acid in the production of polyesters. It can also be converted to gamma-valerolactone, 2,5-furandicarboxylic acid or 2,5-bis(hydroxymethyl)furan. (wikipedia.org).
