ABSTRACT:
The present invention is directed to a process for producing dienes which involves reacting a reaction mixture of tertiary alkyl ether and a source of oxygen over two functionally distinct catalysts under reaction conditions sufficient to produce high yields of the dienes with minimal recycle of the ether. The two functionally different catalysts are selected from a group of bifunctional catalysts having both oxidation sites and acidic sites and monofunctional acidic catalysts, such as bifunctional catalysts containing components selected from a group of oxides of vanadium, tungsten, molybdenum, copper, iron, chromium, and uranium and mixtures thereof; and monofuctional acid catalysts such as acid treated montmorillonite clays, and acid catalysts comprising an inorganic amorphous or substantially amorphous oxide material comprising the following components reacted therein:
