Tunable selectivity of phenol hydrogenation to cyclohexane or cyclohexanol by a solvent-driven effect over a bifunctional Pd/NaY catalyst

, 2021
Hydrogenation of phenol is an important strategy to produce cyclohexane or cyclohexanol as both of them are raw materials for the synthesis of nylon-6 and nylon-66. Herein, we report a novel method for the selective hydrogenation of phenol to cyclohexane

Flexible NiCo-based catalyst for direct hydrodeoxygenation of guaiacol to cyclohexanol

, 2020
The catalytic hydrodeoxygenation (HDO) of lignin-derived phenols is an important step for bio-oil upgrading. Herein, a novel HDO system was established in the presence of nitrogen, instead of traditional hydrogen.

Selective hydrodeoxygenation of lignin-derived phenolic monomers to cyclohexanol over tungstated zirconia supported ruthenium catalysts.

ChemSusChem
The selective hydrodeoxygenation (HDO) of lignin-derived methoxyphenols to cyclohexanol is one of the most significant transformation in biomass conversion since cyclohexanol is an important industrial raw material.

Selective oxidation of cyclohexane to cyclohexanol by BiOI under visible light: Role of the ratio (1 1 0)/(0 0 1) facet

Applied Catalysis B: Environmental, 2019
The development of semiconductors capable of photocatalytic activity under visible light is very important, because such materials are potentially useful for performing photocatalytic conversion under solar illumination.

Cyclohexanols of halleria lucida

Phytochemistry, 1986
Abstract From the stems of Halleria lucida a new 1,4-yclohexandiol, a tranS -1-(2′-hydroxyethyl)cyclohexan-1,4-diol named isorengyol, together with the known cis isomer rengyol, was isolated. The leaves of the same plant contain acteoside, rutin, luteolin-5- O -glucoside and a 4-hydroxy-4-(2′-hydroxyethyl)cyclohexanone, of which the hemiketalic ...

Polystyrene-Based Hierarchically Macro–Mesoporous Solid Acid: A Robust and Highly Efficient Catalyst for Indirect Hydration of Cyclohexene to Cyclohexanol by a One-Pot Method under Mild Conditions

, 2020
As a promising synthesis route, indirect hydration of cyclohexene into cyclohexanol by heterogeneous catalysts shows high conversion than that in direct hydration; however, increasing the yield of cyclohexanol from cyclohexene is still a significant ...
