A process for continuously operated purification by distillation under reduced pressure result of the in the case of the coupler - product-free propylene oxide synthesis solvent used of methanol with simultaneous separation of the methoxy propanols

摘要

A process for continuously operated purification by distillation under reduced pressure result of the in the case of the propylene oxide synthesis by reacting a hydroperoxide with propylene used as solvent methanol under simultaneous separation of the methoxy propanols as an azeotrope with water as well as the slightly - and high boilers are separated, characterized in that the in the case of the synthesis of the solvent mixture obtained is separated in a dividing wall column.
