Kinetics of 4-tert-butylphenol hydrogenation over rhodium
The kinetics of the liquid phase hydrogenation of 4‐tert‐butylphenol to form cis‐ and trans‐ 4‐tert‐butylcyclohexanol at 1.0–10.0 MPa and 40°C in isopropanol over a Rh catalyst has been studied. The kinetic behavior of this parallel system is described by a proposed reaction network. Keto‐enol tauto...

| Zusammenfassung: | The kinetics of the liquid phase hydrogenation of 4‐tert‐butylphenol to form cis‐ and trans‐ 4‐tert‐butylcyclohexanol at 1.0–10.0 MPa and 40°C in isopropanol over a Rh catalyst has been studied. The kinetic behavior of this parallel system is described by a proposed reaction network. Keto‐enol tautomeric transformation of adsorbed 4‐tert‐butyltetrahydrophenol and 4‐tert‐butylcyclohexanone is thought to be a key step, which governs the stereoselectivity of the overall complex reaction of alkylphenol hydrogenation. |
