Abstract

1,236,705. Oxidative dehydrogenation. FIRESTONE TIRE & RUBBER CO. 11 March, 1969 [29 March, 1968], No. 12840/69. Heading C5E. C 4-7 mono-olefins (including cyclohexene) are converted to corresponding conjugated diolefins by oxidative dehydrogenation at 350- 650‹ C. in the presence of a catalyst comprising a mixture of oxides of molybdenum, bismuth and at least one of lanthanum, neodymium, praseodymium, samarium and gadolinium. The catalyst may be supported, e.g. on silica or alumina. A diluent gas may be present, e.g. N 2 , A, CO 2 or (preferably) steam. Examples relate to the production of butadiene andisoprene.
