ALSAIARI, Raiedhah Abdullah. Oxidation of 1-hexene using supported ruthenium catalysts under solvent-free conditions. S.Afr.j.chem. (Online) [online]. 2024, vol.78, pp.61-66. ISSN 1996-840X.  http://dx.doi.org/10.17159/0379-4350/2024/v78a09.

The study evaluated the solvent-free oxidation of 1-hexene utilizing supported ruthenium catalysts and a small amount of terbutyl hydroperoxide (TBHP) as a radical initiator. The characteristics of the supported catalysts were characterized using transmission electron microscopy (TEM) and N₂ adsorption-desorption isotherms. The results of the study revealed that 1% Ru/TiO₂ had favorable catalytic performance when subjected to environmentally friendly reaction conditions. This behavior was thought to be a result of Ru spreading and loading on the TiO₂. To obtain optimal reaction parameters, the catalyst manufacturing process, temperature, reaction time, type of support, and activating amount were tuned. Compared to catalysts generated using wet-impregnation and precipitation techniques, those produced using sol-immobilization have greater activity.
