One embodiment of the present application provides a method for producing butadiene, the method including a step for introducing reactants, including butene, oxygen, nitrogen, and steam, into a reactor filled with a catalyst, and thereby causing an oxidative dehydrogenation reaction, wherein during the initial start-up of the oxidative dehydrogenation reaction, the oxygen is introduced into the reactor before butene, or the oxygen is introduced into the reactor at the same time as butene. La présente invention concerne, dans un mode de réalisation, un procédé de production de butadiène, le procédé comprenant une étape d'introduction de réactifs, comprenant du butène, de l'oxygène, de l'azote, et de la vapeur, dans un réacteur chargé d'un catalyseur, ce qui amène une réaction de déshydrogénation oxydative, où durant le démarrage initial de la réaction de déshydrogénation oxydative, de l'oxygène est introduit dans le réacteur avant le butène, ou de l'oxygène est introduit dans le réacteur en même temps que le butène. 본 출원의 일 실시상태는, 부텐, 산소, 질소 및 스팀(steam)을 포함하는 반응물을, 촉매가 충진된 반응기에 투입하여 산화적 탈수소화 반응시키는 공정을 포함하고, 상기 산화적 탈수소화 반응의 최초 스타트업(start-up)시, 상기 산소를 부텐보다 반응기에 먼저 투입하거나, 상기 산소를 부텐과 동시에 반응기에 투입하는 것인 부타디엔의 제조방법을 제공한다.
