process for producing isobutylene by oxidative dehydrogenation of isobutane

摘要

The present invention aims at providing a process for producing isobutylene with a high selectivity by oxidative dehydrogenation of isobutane. In a process for producing isobutylene by oxidative dehydrogenation of isobutane in the gas phase with molecular oxygen, a catalyst is used which comprises the oxide of phosphorus and the oxide of at least one element selected from the group consisting of zinc, nickel, iron, chromium, vanadium, manganese, cobalt, silver, copper, magnesium, lithium, scandium, titanium, gallium, yttrium, zirconium, antimony, lanthanum, cerium, samarium, ytterbium, hafnium and lead.
