摘要:
A method for producing propylene oxide comprising a step of reacting hydrogen peroxide with propylene in the presence of an epoxidation catalyst in a liquid phase to produce propylene oxide and a step of recovering a recyclable constituent in a vent gas generated in the above step by absorbing the recyclable constituent in a solvent containing a nitrile.
