摘要： Disclosed is a process for purifying propylene oxide. A stream S0 containing propylene oxide, acetonitrile, water, and an organic compound containing one or more of acetone and propionaldehyde is provided. Propylene oxide is separated from S0 by subjecting S0 to distillation in a first distillation unit, obtaining a gaseous top stream S1c enriched in propylene oxide, a liquid bottom stream S1a enriched in acetonitrile and water, and a side stream S1b containing propylene oxide and enriched in the carbonyl compound; reacting the carbonyl compound in S1b with an organic compound containing an amino group to obtain a reaction product; separating propylene oxide from the reaction product in a second distillation unit, obtaining a gaseous top stream S3a enriched in propylene oxide and a liquid bottoms stream S3b enriched in the reaction product; and introducing stream S3a into the first distillation unit.

摘要： The present invention is related to a process for preparing propylene oxide, comprising (i) providing a stream comprising propene, hydrogen peroxide or a source of hydrogen peroxide, water, and an organic solvent; (ii) passing the liquid feed stream provided in (i) into an epoxidation zone comprising an epoxidation catalyst comprising a titanium zeolite, and subjecting the liquid feed stream to epoxidation reaction conditions in the epoxidation zone, obtaining a reaction mixture comprising propene, propylene oxide, water, and the organic solvent; (iii) removing an effluent stream from the epoxidation zone, the effluent stream comprising propylene oxide, water, organic solvent, and propene; (iv) separating propene from the effluent stream by distillation, comprising (iv.1) subjecting the effluent stream to distillation conditions in a distillation unit, obtaining a gaseous top stream S0 enriched in propene compared to the effluent stream subjected to distillation conditions, and a liquid bottoms stream S01 enriched in propylene oxide, water and organic solvent compared to the effluent stream subjected to distillation conditions; (iv.2) returning a condensed portion of the stream S0 to an upper part of the distillation unit.
