    Abstract: A dividing wall distillation column for producing high-purity 2-ethyl hexanol including a condenser, a reboiler and a main column having a dividing wall. The main column is divided into a column-top zone, an upper feed zone, an upper outflow zone, a lower feed zone, a lower outflow zone and a column-bottom zone. A crude 2-ethyl hexanol raw material (F) flows in a middle inflow plate NR1 in which the upper feed zone and the lower feed zone come in contact with each other, a low boiling point component (D) flows out from the column-top zone, a high boiling point component (B) flows out from the column-bottom zone, and a middle boiling point component (S) flows out through a middle outflow plate NR2 in which the upper outflow zone and the lower outflow zone come in contact with each other, where the middle boiling point component is 2-ethyl hexanol.

    Abstract: The present invention relates to a method for producing butadiene through an oxidative dehydrogenation reaction. The production method according to the present invention may easily regulate an input ratio between oxygen and nitrogen that are used as raw material, such that a loss may be minimized of butadiene that is included in a second fraction stream (purge stream) and discharged to outside of the system. Consequently, an economic competitiveness of the process, such as a reduced raw material cost and an improved productivity may be realized.
