Due to its three hydroxyl groups, glycerol is a potential starting material for various high value fine chemicals such as dihydroxyacetone, tartronic acid and mesoxalic acid. The corresponding oxidation reactions are catalysed by metals palladium, platinum, bismuth or gold. Nevertheless, the selectivity not only depends on type of active phase, but also influenced numerous parameters metal particles size, pore size support pH reaction medium. This review describes recent developments in...
Catalytic dehydration of glycerol to acrolein has the potential valorise glut crude issuing from biodiesel production. This reaction requires catalysts with appropriate acidity, and intensive research activities have been focused on application families including zeolites, heteropolyacids, mixed metal oxides (oxo)-pyrophosphates, as their acidic properties are well-known. Nevertheless, deactivation by coking remains main obstacle in way large-scale industrial applications. Considering this...
Catalytic dehydration is one of the possible reactions to valorize large amounts glycerol yielding from transesterification process. Thus, since biodiesel boom in 2004–2005, many publications proposing various catalytic systems can be found. In this review, current state art based on most recent presented and discussed detail with respect observed performance as well long-term stability. Next applied development new catalysts, a main focus influence critical parameter: acidity catalyst its...
Aliphatic PNP pincer-supported earth-abundant manganese(I) dicarbonyl complexes behave as effective catalysts for the acceptorless dehydrogenative coupling of a wide range alcohols to esters under base-free conditions. The reaction proceeds neat conditions, with modest catalyst loading and releasing only H2 byproduct. Mechanistic aspects were addressed by synthesizing key species related catalytic cycle (characterized X-ray structure determination, multinuclear (1H, 13C, 31P, 15N, 55Mn) NMR,...
This review paper delves into synergistic integration of artificial intelligence (AI) and machine learning (ML) with high-throughput experimentation (HTE) in the field heterogeneous catalysis, presenting a broad spectrum contemporary methodologies innovations. We methodically segmented text three core areas: catalyst characterization, data-driven exploitation, discovery. In characterization part, we outline current prospective techniques used for HTE how AI-driven strategies can streamline...
This review paper presents the current state of art on maleic acid synthesis from biomass-derived chemicals over homogeneous or heterogeneous catalysts. It is based most recent publications topic, which are discussed in details with respect to observed catalytic performances. The developments and technical drawbacks gas liquid phases also reported. In addition, results mechanistic aspect giving insights into probable reaction mechanisms depending starting molecule (furan, furfural...
Catalytic conversion of ethanol is a promising technology for producing sustainable butadiene. This paper reviews the reaction and its catalysts, discusses challenges their development faces.
1,3-Butadiene is traditionally produced as a byproduct of ethylene production from steam crackers. What unusual that the alternative route for this important commodity chemical via ethanol was developed long time ago, before World War II. Currently, there renewed interest in butadiene biomass due to general trend replace oil industry. This review describes recent progress (ETB) by one or two-step process through intermediate acetaldehyde with an emphasis on new catalytic systems. The...
HAP solids were prepared with different Ca/P ratios and Na<sup>+</sup>cations before being characterized by XRD, XPS, LEIS, NMR, IR, TGA. Their acid–base properties then measured discussed in relation to the characterization results.
Abstract The catalytic conversion of alcohols into carboxylic acid salts in water was performed the presence ruthenium complexes supported by aliphatic PNP pincer ligands preformed or formed situ. High activity toward a wide substrate scope achieved with turnover number values up to 4000. air‐stable system can be recycled using toluene as catalyst‐immobilizing phase; is maintained after five consecutive runs. Finally, mechanistic studies allowed some fundamental aspects related activation...
While the initial catalytic performances of silica-supported silicotungstic acid are high in glycerol dehydration reaction, they rapidly decrease with time on stream and acrolein yield quickly decreases.
The gas phase decarbonylation of lactic acid was performed over various silica-supported heteropolyacids. obtained performances were, by far, higher than those previously described in the literature. In particular, best results were for silicotungstic acid-based catalysts, which showed very high yields acetaldehyde (81–83%) at conversion (up to 91%).
