ABSTRACT:
A process is used to dehydrogenate organic compounds to a higher degree of unsaturation by contacting in a first step, the organic compound with a calcined zinc titanate catalyst modified with lithium or magnesium. In the second step, the catalyst is contacted with oxygen essentially in the absence of the dehydrogenatable organic compound. The first and second steps are repeated sequentially.
