There is disclosed a method comprising the oxidative dehydrogenation of at least one hydrocarbon selected from the group consisting of butene-1, butene-2, 2-methyl-1-butene, 2-methyl-2-butene, 3-methyl-1-butene, n-pentene, 2,3-dimethyl-1-butene, 2,3-dimethyl-2-butene, 2-methyl-1-pentene, 2-methyl-2-pentene, 4-methyl-2-pentene, 3-methyl-1-pentene, 3-methyl-2-pentene, 2-ethyl-1-butene, ethyl benzene and isopropyl benzene at oxidative dehydrogenation conditions while in the presence of a catalyst comprising cobalt-molybdate which has enhanced activity by being calcined at temperatures from 750 DEG -1100 DEG C for at least one hour prior to use in the oxydehydrogenation process. |
