“…The produced acetone can be rehydrogenated to isopropanol with hydrogenation catalysts. For example, Raney nickel catalyst showed 99.9% conversion of acetone and 99.9% selectivity of isopropanol in the liquid phase . In addition to the conversion of isopropanol to acetone, dehydration of isopropanol also occurred, producing some of propene (0.2 mmol) and diisopropyl ether (1.8 mmol) in the reaction solution (Table S4).…”

Renewable adipic acid is a value-added chemical for the production of bioderived nylon. Here, the one-step conversion of mucic acid to adipates was achieved in high yield through deoxydehydration (DODH) and catalytic transfer hydrogenation (CTH) by a bifunctional Pt-ReO x /C heterogeneous catalyst with isopropanol as solvent and reductant. The Pt-ReO x /C catalyst is reusable and was regenerated at least five times. The catalyst exhibits a broad substrate scope of various diols. Spectroscopic studies of Pt-ReO x /C revealed Re VII and Pt 0 as the relevant species for DODH and CTH, respectively. Isotope labeling experiments support a monohydride mechanism for CTH over Pt. This work demonstrates a reusable bifunctional catalyst for a one-step valorization of sugar acids to a practical monomer, which opens the door to multifunctional catalysis streamlining valorization of biomass-derived molecules.

“…1-Propanol is manufactured at the industrial level from the reduction of propanal ( 21 ), itself produced from the hydroformylation of petro-based ethylene. It comes with a broad range of applications, including its use as a solvent . Zhu and coworkers demonstrated both the selective conversions of 1,2-PDO and 1,3-PDO into 1-propanol over a Cu–Ce–SBA catalyst .…”

The ever increasing industrial production of commodity and specialty chemicals inexorably depletes the finite primary fossil resources available on Earth. The forecast of population growth over the next 3 decades is a very strong incentive for the identification of alternative primary resources other than petro-based ones. In contrast with fossil resources, renewable biomass is a virtually inexhaustible reservoir of chemical building blocks. Shifting the current industrial paradigm from almost exclusively petro-based resources to alternative bio-based raw materials requires more than vibrant political messages; it requires a profound revision of the concepts and technologies on which industrial chemical processes rely. Only a small fraction of molecules extracted from biomass bears significant chemical and commercial potentials to be considered as ubiquitous chemical platforms upon which a new, bio-based industry can thrive. Owing to its inherent assets in terms of unique process experience, scalability, and reduced environmental footprint, flow chemistry arguably has a major role to play in this context. This review covers a selection of C2 to C6 bio-based chemical platforms with existing commercial markets including polyols (ethylene glycol, 1,2-propanediol, 1,3-propanediol, glycerol, 1,4-butanediol, xylitol, and sorbitol), furanoids (furfural and 5-hydroxymethylfurfural) and carboxylic acids (lactic acid, succinic acid, fumaric acid, malic acid, itaconic acid, and levulinic acid). The aim of this review is to illustrate the various aspects of upgrading bio-based platform molecules toward commodity or specialty chemicals using new process concepts that fall under the umbrella of continuous flow technology and that could change the future perspectives of biorefineries.

“…Additionally, isopropanol can be obtained from biomass materials, making it more environmentally friendly than the linear isomer [ 59 , 193 ]. Both propanol isomers on an industrial scale are produced by hydrogenation—isopropanol is a result of the hydrogenation of acetone (reaction (36)), and propanol is obtained by the hydrogenation of propanal (reaction (37)) [ 92 ]: CH 3 C(O)CH 3 + H 2 → CH 3 CH(OH)CH 3 CH 3 CH 2 CHO + H 2 → CH 3 CH 2 CH 2 OH …”

The growing climate crisis inspires one of the greatest challenges of the 21st century—developing novel power sources. One of the concepts that offer clean, non-fossil electricity production is fuel cells, especially when the role of fuel is played by simple organic molecules, such as low molecular weight alcohols. The greatest drawback of this technology is the lack of electrocatalytic materials that would enhance reaction kinetics and good stability under process conditions. Currently, electrodes for direct alcohol fuel cells (DAFCs) are mainly based on platinum, which not only provides a poor reaction rate but also readily deactivates because of poisoning by reaction products. Because of these disadvantages, many researchers have focused on developing novel electrode materials with electrocatalytic properties towards the oxidation of simple alcohols, such as methanol, ethanol, ethylene glycol or propanol. This paper presents the development of electrode materials and addresses future challenges that still need to be overcome before direct alcohol fuel cells can be commercialized.
