The present invention relates to a butadiene production method and, more specifically, to a method for producing butadiene by introducing butene and oxygen into a reactor having a metal composite oxide catalyst therein and subjecting same to oxidative dehydrogenation, the butadiene production method being characterized in that the molar ratio of butene to oxygen is 1.8 to 2.2. The present invention has the effect of providing a butadiene production method which secures long-term operational stability by maintaining the strength of a catalyst even if subjected to oxidative dehydrogenation and does not diminish selectivity by reducing a side reaction. La présente invention concerne un procédé de production de butadiène et, plus spécifiquement, un procédé de production de butadiène consistant à introduire du butène et de l'oxygène dans un réacteur contenant un catalyseur d'oxyde composite métallique et à soumettre celui-ci à une déshydrogénation oxydative, le procédé de production de butadiène étant caractérisé en ce que le rapport molaire de butène à l'oxygène est de 1,8 à 2,2. La présente invention a pour but de réaliser un procédé de production de butadiène qui assure une stabilité de fonctionnement à long terme en maintenant la résistance d'un catalyseur, même si celui-ci est soumis à la déshydrogénation oxydative et ne fait pas diminuer la sélectivité par réduction d'une réaction secondaire. 본 발명은 부타디엔 제조방법에 관한 것으로, 보다 상세하게는 부텐과 산소를 금속 복합산화물 촉매가 내장된 반응기에 투입하고 산화 탈수소화 반응시켜 부타디엔을 제조하는 방법에 있어서, 상기 부텐과 산소의 몰비가 1.8 내지 2.2인 것을 특징으로 하는 부타디엔 제조방법에 관한 것이다. 본 발명에 따르면, 산화 탈수소화 반응에도 촉매의 강도가 유지되어 장시간 운전 안정성이 확보되고, 또한 부반응이 적어 선택도가 저하되지 않는 부타디엔 제조방법을 제공하는 효과가 있다.
