The Stereochemistry of Autoxidation of Methylcyclohexanes [PDF]

Bulletin of the Chemical Society of Japan, 1975
Abstract Autoxidation of 1, c-3, c-5- or 1, c-3, t-5-trimethylcyclohexane with oxygen in the presence of azobisisobutyronitrile at 60°C and subsequent reduction with lithium aluminium hydride gave 1, t-3, t-5- and 1, c-3, c-5-trimethyl-r-1-cyclohexanol in the same ratio of 1/0.85.

Toluene hydrogenation and ring-opening on bimetallic Pd-Pt/HY catalysts

Revista UIS Ingenierías, 2023
Bimetallic Pd-Pt/HY catalysts prepared by the co-impregnation method with an atomic variation of Pd/Pd+Pt were studied to convert toluene and methylcyclohexane. The catalysts were characterized by the BET method, chemisorption of CO by the pulse method,

CO-tolerant RuNi/TiO2 catalyst for the storage and purification of crude hydrogen

Nature Communications, 2022
Efficient storage of crude hydrogen, through toluene hydrogenation to methylcyclohexane, is often inhibited by CO impurities. Here, the authors develop a RuNi/TiO2 catalyst which avoids deactivation through promoting simultaneous CO methanation.

Energy efficiency of a hydrogen supply system using the reaction cycle of methylcyclohexane-toluene-hydrogen

Mechanical Engineering Journal, 2017
In this research, we investigated an energy supply system based on hydrogen derived from renewable energy. We modeled the energy flow and efficiency of a system using the MCH-toluene-hydrogen reaction cycle (MTHR) by methylcyclohexane (MCH, C6H11CH3) and
