Selective Aerobic Oxidation of 5-Hydroxymethylfurfural in Water Over Solid Ruthenium Hydroxide Catalysts with Magnesium-Based Supports

Abstract: Solid catalyst systems comprised of ruthenium hydroxide supported on magnesium-based carrier materials (spinel, magnesium oxide and hydrotalcite) were investigated for the selective, aqueous aerobic oxidation of the biomass-derived chemical 5-hydroxymethylfurfural into 2,5-furandicarboxylic acid (FDA), a possible plastics precursor. The novel catalyst systems were characterized by nitrogen physisorption, XRPD, TEM and EDS analysis, and applied for the oxidation with no added base at moderate to high pressures … Show more

“…[20] The addition of aH Tass olid base even increased the FDCA yield. Experiments conducted with 18 O 2 revealed water as the source of oxygen for the oxidation of the formyl group as already discussed for HMF oxidation overP ta nd Au catalysts. [27] For comparison with the system presented by Nie et al,k nowledgeo ft he exact reaction times utilized in their study would be necessary,whichare not provided in the publication.…”

“…Soluble metal bromide catalysts (Co/Mn/ Br) in acetic acid, normally employed for the conventional oxidation of para-xylene to terephthalic acid, have been tailored for the HMF oxidation. [12,13] Also, recoverable supported metallic nanoparticles, mainly Pt-, [14][15][16][17] Ru-, [18,19] and Au-based, [20][21][22][23][24] and bimetallic catalysts [25][26][27] that permit the reaction in an aqueous medium by using molecular oxygen or air have been investigated.…”

“…Combined, the activity drop as well as the increased surface area could indicate possible Ru leaching from the support to the reaction solutions. However, leaching of Ru from this type of catalyst materials under similar conditions has previously shown to be a minor issue [39][40]. Continuation of the work is currently in progress in search for a suitable water-tolerant and stable supported catalyst.…”
