    Abstract: The present invention is related to a process for purifying propylene oxide, comprising (i) providing a stream (S0) comprising propylene oxide, acetonitrile, water, and an organic compound comprising a carbonyl group -C(=O)-, wherein said organic compound comprising a carbonyl group -C(=O)- comprises one or more of acetone and propionaldehyde; (ii) separating propylene oxide from the stream (S0) by distillation, comprising subjecting the stream (S0) to distillation conditions in a distillation column, obtaining a gaseous top stream (S1c) which is enriched in propylene oxide compared to the stream (S0), a liquid bottoms stream (S1a) which is enriched in acetonitrile and water compared to the stream (S0), and a side stream (S1b) comprising propylene oxide which is enriched in the carbonyl compound compared to the stream (S0); wherein the distillation column is operated at an absolute pressure at the top of the distillation column in the range of from 0.01 to 0.2 MPa (0.1 to 2.0 bar) and an internal reflux ratio in the range of from 2.0 to 6.0; wherein the distillation column exhibits at least 100 theoretical trays, the rectifying section of the distillation column consists of from 30 to 70 % of the theoretical trays and the stripping section of the distillation column consists of from 70 to 30 % of the theoretical trays.
