Abstract: Partial oxidation products and/or ammoxidation products of an olefinic hydrocarbon A' are prepared by a process in which said olefinic hydrocarbon is produced during normal operation by partial dehydrogenation and/or oxydehydrogenation of hydrocarbon A and fed in from another source during partial or complete nonoperation of the dehydrogenation and/or oxydehydrogenation.

Abstract: The disclosure involves a process for the preparation of butadiene and 1-butene. The process includes at least a first catalytic dehydrogenation of n-butane to obtain a gas stream which is followed by at least a second oxidative dehydrogenation to form a second gas stream. The second gas stream is then subjected to distillation and isomeration steps to obtain butadiene and 1-butene.
