Abstract: There are provided a dividing wall distillation column for producing high-purity 2-ethyl hexanol, and a fractional distillation method using the same. The dividing wall distillation column includes a condenser, a reboiler and a main column having a dividing wall. Here, 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. Also, 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. In this case, the middle boiling point component is 2-ethyl hexanol. Accordingly, since one distillation column can be used to realize the same effect as that obtained from the use of two distillation columns, the dividing wall distillation column can have an effect of reducing the costs of equipment to produce high-purity 2-ethyl hexanol, as well as an energy-reducing effect, compared to a conventional process system.
