摘要：
The present disclosure relates to a dividing wall distillation column and a method for refining vinylidene dichloride by using the same and, more specifically, to a dividing wall distillation column capable of refining, in a high purity, vinylidene dichloride from a crude product; and a method for refining vinylidene dichloride by using the same. According to the dividing wall distillation column of the present disclosure and the method for refining vinylidene dichloride by using the same, vinylidene dichloride can be refined, in a high purity, from a crude product having a small amount of vinylidene dichloride and a large quantity of high boiling components, and energy consumption can be reduced more than that in conventional cases.
