One-step synthesis of 2-pentanone from ethanol over K-Pd/MnOx-ZrO2-ZnO catalyst

Biomass-derived 2-methyltetrahydrofuran platform: a focus on precious and non-precious metal-based catalysts for the biorefinery

Transition Metal B-Site Substitutions in LaAlO3 Perovskites Reorient Bio-Ethanol Conversion Reactions

“…It is tempting to attribute this effect to the higher reducibility of these catalysts (Figure 2). Mixed oxide catalysts for the synthesis of acetone or pentanone from acetaldehyde are often pre-reduced in H 2 flow before the reaction [30,95]. This treatment has not been applied in our experiments.…”

“…Ethanol conversion pathways through acetaldehyde lead to the formation of butanol (a performant biofuel) by the Guerbet reaction [14][15][16][17][18][19] or of butadiene (a major component of elastomers) through the time-honored and recently revamped Ostromislensky and Lebedev processes [20][21][22][23][24][25]. Successive reactions of acetaldehyde, through coupling with ethanol, aldol coupling and ketonisation, lead to the formation of relevant oxygenated solvents, as ethyl acetate [26,27], acetone [28,29] and 2-pentanone [30]. Propylene (another major monomer for polyolefins) can also be produced from acetaldehyde-derived acetone [31,32].…”
