Summary:PCT No. PCT/EP96/04818 Sec. 371 Date May 18, 1998 Sec. 102(e) Date May 18, 1998 PCT Filed Nov. 5, 1996 PCT Pub. No. WO97/19069 PCT Pub. Date May 29, 1997A process for distilling ethylene oxide out of a mixture including ethylene oxide in a column at an absolute pressure of from 2 to 10 bar and a temperature of 20 to 180 DEG C. by withdrawing pure ethylene oxide in the liquid or gaseous state overhead or via a sidestream in the rectifying section of the column includes effecting the distillation in a column having on its inside a plurality of successive zones of structured sheet-metal packing or dumped beds of packing elements, these zones being assigned one or more extinguishing systems on the outside of the column.
