Mixed oxides based on MgO⋅CeO2 were used as efficient catalysts in the aerobic oxidation of 5-hydroxymethylfurfural (5-HMF) to afford, with very high selectivity, either 2,5-diformylfuran (DFF, 99 %) or 2-formyl-5-furancarboxylic acid (FFCA, 90 %), depending reaction conditions. 5-Hydroxymethyl-2-furancarboxylic (HMFCA, 57-90 was formed only at low concentration 5-HMF (<0.03 m) presence external bases. The conversion ranged from a few percent %, according performed water, O2 oxidant, without...
The selective oxidation of 5-HMF towards 2,5-furandicarboxylic acid (FDCA) has been achieved with 99% yield in water, using oxygen as the oxidant over CuO·MnO<sub>2</sub>·CeO<sub>2</sub>mixed oxides.
Abstract Aqueous glycerol was used as the hydrogen source for reduction of CO 2 to carrier formic acid in presence catalyst [RuCl (PPh 3 ) ]. All intermediates were identified and characterized. Glycerol converted into glycolic acid, HOCH COOH, that by using 1 H 13 C NMR spectroscopy.
Abstract The sustainable chemical industry encompasses a shift from the use of fossil carbon to renewable carbon. synthesis chemicals nonedible biomass (cellulosic or oil) represents one key steps for “greening” industry. In this paper, we report aerobic oxidative cleavage C6 polyols (5‐HMF, glucose, fructose and sucrose) oxalic acid (OA) succinic (SA) in water under mild conditions using M@CNT M@NCNT (M=Fe, V; CNT=carbon nanotubes; NCNT=N‐doped CNT), which, suitable conditions, were...
5-Hydroxymethylfurfural (5-HMF) can be considered a prominent building block: because of the presence alcohol and aldehyde moieties, it used to generate useful molecules as chemicals industrial interest with high added value, monomers for polymers, even fuels. This article shows how up mixed oxides different complexities properties may drive selectivity toward one possible products generated from 5-HMF. In particular, based on cerium other metals abundant earth-crust perform selective...
In this paper, we describe the use of a MnO2@CeO2 core–shell oxide in furfural oxidation into furoic acid with molecular oxygen water as solvent. MnO2 is active oxidant species. The catalyst was prepared using two different synthetic procedures (high energy milling, HEM; or microwave-assisted hydrothermal, MWHT), and activity samples compared that commercial MnO2. MWHT exhibits excellent catalytic properties (conversion furaldehyde >95% selectivity equal to 100%) almost no Mn-leaching over...
Abstract Oxazolidinones have been synthesized by reacting glycerol carbonate or with urea in the presence of γ‐Zr phosphate as a catalyst. The conversion yield polyol its depends on temperature. Below 408 K selectivity is 100 % up to 25 %, whereas increasing temperature means that grows, but decreases, which makes separation process more difficult. Starting from carbonate, two isomers, 6 and 6′ , are formed quasi 1:1 molar ratio because can attack moiety both sides carboxylic CO moiety. From...
Semiconductor materials are the basis of electronic devices employed in communication and media industry. In present work, we report synthesis characterization mixed metal oxides (MOs) as p,n-junction photocatalysts, demonstrate correlation between preparation technique properties materials. Solid-state UV-visible diffuse reflectance spectroscopy (UV-VIS DRS) allowed for determination light absorption optical energy gap.
