Abstract: A process is proposed for distilling ethylene oxide from a mixture containing ethylene oxide in a column at an absolute pressure of 2-10 bar and a temperature of 20-180 DEG C; pure ethylene oxide is removed at the top or through a side discharge in the column and distillation takes place in a column divided up internally into a number of successive zones with structured sheet metal packs or piles of fillers, one or more quenching systems located outside the column being allocated to said zones.
