Ionic hydrogenation of olefins on heterogeneous catalysts
- 29 Downloads
The heterogeneous catalysts PtO2 and Pd/C differ in the mechanism of their activity as a function of the acidity of the medium.
Olefins branched at the ethylene carbon atom are hydrogenated in sufficiently acid mediums with the transfer of a hydride ion by the catalyst to an intermediately formed carbocation.
Preferential hydrogenation of branched olefins in the presence of unbranched olefins was carried out for the first time on heterogeneous catalysts.
