Abstract

The invention relates to a method and a device for separating a substance mixture into three component parts thereof by extractive distillation. In order to reduce the amount of energy and investment required, the extractive distillation is carried out introduced into a distillation column embodied in the form of a separating wall column (K1). As a result it is possible to obtain three products (P1, P2, P3) with a high degree of purity in a single distillation step even when the substance mixtures are close-boiled.
