    Abstract: The invention relates to a process for preparing butadiene from n-butenes having a start-up phase and an operating phase, wherein the process in the operating phase comprises the steps: A) provision of a feed gas stream a1 comprising n-butenes; B) introduction of the feed gas stream a1 comprising n-butenes, of an oxygen-comprising gas stream a2 and of an oxygen-comprising recycle gas stream d2 into at least one oxidative dehydrogenation zone and oxidative dehydrogenation of n-butenes to butadiene, giving a product gas stream b comprising butadiene, unreacted n-butenes, water vapor, oxygen, low-boiling hydrocarbons, high-boiling secondary components, possibly carbon oxides and possibly inert gases; C) cooling and compression of the product gas stream b and condensation of at least part of the high-boiling secondary components, giving at least one aqueous condensate stream c1 and a gas stream c2 comprising butadiene, n-butenes, water vapor, oxygen, low-boiling hydrocarbons, possibly carbon oxides and possibly inert gases; D) introduction of the gas stream c2 into an absorption zone and separation of incondensable and low-boiling gas constituents comprising oxygen, low-boiling hydrocarbons, possibly carbon oxides and possibly inert gases as gas stream d from the gas stream c2 by absorption of the C
    4 -hydrocarbons comprising butadiene and n-butenes in an absorption medium, giving an absorption medium stream loaded with C
    4 -hydrocarbons and the gas stream d, and recirculation, optionally after separating off a purge gas stream p, of the gas stream d as recycle gas stream d2 to the oxidative dehydrogenation zone; and the start-up phase comprises the steps: i) introduction of an oxygen-comprising gas stream and an inert gas stream into the dehydrogenation zone in such a ratio that the oxygen content of the recycle gas stream d2 corresponds to up to 80% of the oxygen content of the recycle gas stream d2 in the operating phase; ii) setting of the recycle gas stream d2 to at least 70% of the volume flow of the recycle gas in the operating phase; iii) optional introduction, at an initial oxygen content of the recycle gas stream d2 of from 30 to 80% of the oxygen content of the recycle gas stream d2 in the operating phase, of a steam stream a3 into the dehydrogenation zone; iv) introduction, at an initial oxygen content of the recycle gas stream d2 of from 30 to 80% of the oxygen content of the recycle gas stream d2 in the operating phase, of an oxygen-comprising gas stream a2' and a butene-comprising feed gas stream a1' having smaller volume flows than in the operating phase in a ratio k = a2'/a1' and raising of the volume flows of the gas streams a1' and a2' until the volume flows of the gas streams a1 and a2 in the operating phase are obtained, with the recycle gas stream d2 being at least 70% and not more than 120% of the volume flow in the operating phase.
