“…The impact of the hydrophilic–hydrophobic properties of the catalysts on the base-free aerobic oxidation of ethanol was investigated. ,,, Richter et al investigated the catalytic performance of the hydrophobic Pt/SPDVB, obtained by gas-phase sulfonation of Pt/PDVB, in a batch reactor at 363 K and 1 MPa in 24 h experiments. These authors found no differences with the outcomes attained using the hydrophilic Pt/PDVB catalyst.…”

“…Horowitz and co-workers , performed the aerobic oxidation of ethanol in a bench scale trickle-bed reactor (TBR) using Pt supported on 3 mm γ-Al 2 O 3 spheres at 343 K and 0.1 MPa (Table S1, entry17). They compared ethanol conversions attained in the TBR packed either with 100%Pt/Al 2 O 3 (1 wt %) (hydrophilic), with 100% Pt/Al 2 O 3 (1 wt %) covered with Teflon (hydrophobic) or with mixtures of hydrophobic catalyst and hydrophilic γ-Al 2 O 3 spheres.…”

“…In a subsequent work, these authors showed that mixing a resin solid acid catalyst with Pd/SBD favored the esterification reaction of acetic acid to produce ethyl acetate, thus increasing the productivity and extending the catalyst lifetime. 70 Horowitz and co-workers 58,69 performed the aerobic oxidation of ethanol in a bench scale trickle-bed reactor (TBR) using Pt supported on 3 mm γ-Al 2 O 3 spheres at 343 K and 0.1 MPa (Table S1, entry17).

There has been a growing interest in the last decades in technologies that transform biomass-derived feedstock into renewable chemicals. A group of target molecules derived from biomass as key intermediates between raw materials and final products have been designed as "platform chemicals". Sustainable processes involve the use of renewable feedstock, but also pursue low energy consumption, the use of less hazardous materials, and diminished generation of waste. This review aims to present recent advances on environmentally friendly catalytic oxidation routes for transforming three platform chemicals, ethanol, glycerol, and 5-hydroxymethylfurfural, to value added intermediates and final products using air or oxygen as oxidants and water without additives (base-free) as solvent, and preferably under moderate operating conditions. Works carried out under continuous flow have been particularly reviewed.

“…Trickle bed reactors are randomly packed fixed-bed tubular reactors traversed cocurrently downwards by gas and liquid streams. They have achieved widespread commercial acceptance in many gasliquid-solid catalytic industrial applications [18,19]. The vast majority of industrial trickle bed reactors operate under extreme conditions such as high pressure in order to handle large gas volumes, to enhance the gaseous reactant solubility in liquids to be processed, and to promote heat and mass transfers [20].…”
