Method for continuously operated pure distillation of oxirane, especially propylene oxide |
摘要 |
The invention relates to a continuously operated process for the purification by distillation of the oxirane formed in the oxirane synthesis by reaction of a hydroperoxide with an organic compound, wherein the crude oxirane is separated in a dividing wall column into low-, intermediate- and high-boiling fractions and the oxirane is taken off as intermediate boiler at the side offtake in a concentration of at least 99.9%.
