| abstract |
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. |
