Catalytic dehydrogenation of ethylbenzene to styrene on cadmium oxide in the presence of water vapor
- 100 Downloads
When ethylbenzene is passed over CdO in the presence of excess water, what is formed is principally styrene. and to a lesser extent, benzene.
Styrene is produced as a result of catalytic dehydrogenation of ethylbenzene (this reaction on CdO is predicted by multiplet theory), as well as as a result of conversion of the ethylbenzene by cadmium oxide. The greater part of the nascent hydrogen reduces CdO.
Catalytic reactions predominate over topochemical reactions, especially in the formation of styrene.
