Catalytic Hydrogenolysis of Solketal on Bifunctional Catalysts with Production of High Octane Components of Motor Fuels

Catalytic Reductive Alcohol Etherifications with Carbonyl‐Based Compounds or CO2 and Related Transformations for the Synthesis of Ether Derivatives

“…Finally, in 2017 Maximov and co‐workers developed a Pd/Al‐HMS bifunctional nanomaterial able to perform direct solketal hydrogenolysis for producing glycerol alkyl ethers (Scheme 14). [120] Related to this contribution, in 2020 they also showed that Pd/C in combination with p ‐TSA or Pd/SO 4 ‐C alone (see Scheme 9, bottom) are active for the same transformation [101] …”

“…In addition to the work by Lemaire and co‐workers, last year Maksimov et al. developed a protocol for the catalytic synthesis of glycerol monoisopropyl ether through the flow hydrogenation of glycerol/acetone mixtures at 120–160 °C [101] . In this work, either Pd/C in combination with p ‐TSA, or a Pd/SO 4 ‐C bifunctional material, were employed as effective systems for the production of the target compound.…”

Remarkably, the glycerol monoethers (GMEs) obtained in these protocols constitute highly interesting compounds due to its applications in cosmetics, cleaning formulations, pharmacy, and personal care, among others.…”

Non-Porous Sulfonic Acid Catalysts Derived from Vacuum Residue Asphaltenes for Glycerol Valorization via Ketalization with Acetone

“…The syntheses and the characterization procedures of the lab-prepared catalysts have been reported elsewhere for the mesoporous aluminosilica Al-HMS (20) with the Si/Al = 20 [30], the SiO 2 -supported F-4SF perfluoropolymer (10 wt% of the supported polymer) [18] and the sulfonated coal [31].…”

“…The data provided by the manufacturer; 2 the three-dimensional structure of the materials is characterized by the two pore types with sizes of 0.76 × 0.64 and 0.55 × 0.55 nm;3 the properties have been previously reported by us for the BEA zeolites and the Al-HMS(20)[30], K-10 [12], SC[31] and the 10 wt% F-4SF/SiO 2[18] .…”
