“…Stabilization of metal nanoparticles in rigid polymers can be an alternative for commonly used oxides or carbon-supported catalysts, providing high product yields along with the improved catalyst stability [5,[10][11][12][13][14][15][16][17][18][19][20]. Hypercrosslinked polystyrene (HPS) is a rigid polymer with high mechanical and chemical stability that can be a good matrix for metal nanoparticle synthesis.…”

The selective hydrogenation of phenol to cyclohexanone has attracted a great deal of attention both in industry and academia. In this review, the significance, strategies and mechanisms for the production of cyclohexanone are briefly described. Then, the evolution of phenol hydrogenation in gas/liquid phase is summarized according to catalyst type. In situ hydrogenation techniques including catalytic transfer hydrogenation (CTH) and electrocatalytic hydrogenation (ECH) of phenol are also discussed. Although the technology for catalyst design has developed rapidly within the past decades, direct evidence to understand the reaction mechanisms and kinetics is still scarce. Therefore, it is still challengingto explore the function mechanisms and design advanced catalysts with high activity and high selectivity (>95%) for direct hydrogenation of phenol to cyclohexanone. This review may provide guidance for these attempts.

“…Cyclohexanol was obtained as the only reaction product after 55 h. Gas-phase hydrogenation of phenol was realized in the same year, with cyclohexanol and cyclohexanone obtained as the main reaction products and benzene, cyclohexane, and cyclohexene as minor reaction products [11]. In industry gas-phase hydrogenation of phenol is carried out at 120-170 • C and hydrogen pressure of 0.3-5 MPa in the presence of Pd/Al 2 O 3 catalyst [3,6,7,[12][13][14][15][16]. This is the main process to obtain cyclohexanone from phenol.…”

“…Hydrogenation of phenol is still an important process in the petrochemical industry, being used to obtain cyclohexanone, the essential feedstock for the synthesis of adipic acid and caprolactam [1][2][3]. Hydrogenation products of substituted phenols are used as feedstock for synthesis of lubricants, additives to oils and fuels, surfactants, and perfumes.…”

Dendrimer-Stabilized Ru Nanoparticles Immobilized in Organo-Silica Materials for Hydrogenation of Phenols

et al. 2017

View full text Add to dashboard Cite

New hybrid catalysts based on Ru nanoparticles, encapsulated into poly(propylene imine dendrimers), immobilized into silica pores, were synthesized and examined for the hydrogenation of alkyl-substituted phenols. The corresponding alkyl-substituted cyclohexanols were presented as the major reaction products, while incomplete hydrogenation products appeared to be minor. A competition between the sterical factors of dendrimer-containing carriers and the electronic factors of substrate substituents influenced the hydrogenation rate of the alkyl-substituted phenols. The carrier structure was found to have a significant influence on both the physical and chemical properties of the catalysts and their hydrogenation activity. The synthesized hybrid catalysts appeared to be stable after recycling and could be re-used several times without significant loss of activity.
