Method for continuously operated pure distillation of oxiranes, especially propylene oxide |
abstract |
The invention relates to a continuously operated method for pure distillation of oxirane arising during oxirane synthesis by reacting hydroperoxide with an organic compound, characterised in that the raw oxirane is separated in a separating wall column in a light, medium and high boiler fraction and removed as a medium boiler at a concentration of at least 99.9 % by lateral extraction. |
