PURPOSE:To provide a production process for isobutylene in high selectivity by oxidative dehydrogenation of isobutane. CONSTITUTION:In the production process for isobutylene by oxidative dehydrogenation of isobutane using molecular oxygen in gas phase, as a catalyst, is used a combination of phosphorus oxide with an oxide of at least one element selected from lithium, scandium, titanium, gallium, strontium, yttrium, zirconium, antimony, cesium, lanthanum, cerium, samarium, europium, ytterbium, hafnium, lead and bismuth. |
