| titleOfInvention | PURIFICATION OF PROPYLENE OXIDE RESULTING FROM THE PROPYLENE EPOXIDATION WITH HYDROGEN PEROXIDE. |
| abstract | A process for separating a purified propylene oxide from a crude epoxidation product produced, preferably in an epoxy reaction of propylene with hydrogen peroxide. The process involves removing the bulk water, bulk methanol, and unreacted propylene from the crude epoxidation product and then subjecting the resulting oxide product to an extractive distillation with water as an extraction solvent. Under distillation conditions, including a bottom temperature greater than about 55degree C and less than about 75degree C, a lateral cut-off or distillate overload flow is obtained containing a purified propylene oxide with a low yield loss of propylene to propylene glycols and other heavy glycol bombardments. The purified propylene oxide can be further purified in a finishing distillation to obtain a propylene oxide that meets commercial grade purity requirements. |
