✦ Synopsis
The oxidative dehydrogenation of ethane, propane and n-butane over a vanadiaÈmolybdenaÈniobia catalyst has been compared with propane substituted in the 2 position with a methyl (isobutane) or a benzyl (isopropylbenzene) group. In the normal paraffins, selectivity to the oleÐn was found to decrease as the chain length increased. Substitution at the propane 2 position increased selectivity, particularly in the case of isopropylbenzene. The results are explained partially in terms of over oxidation of the product oleÐn and partially in terms of structural e †ects in the parent hydrocarbon inÑuencing the oleÐn-producing oxidative dehydrogenation reaction.
