| titleOfInvention | Purification method of propylene oxide |
| abstract | the present invention (i) a stream (SO) comprising propylene oxide, acetonitrile, water, and an organic compound comprising a carbonyl group (-C(=O)-), comprising the carbonyl group (-C(=O)-) providing a stream (SO) wherein the organic compound comprises at least one of acetone and propionaldehyde; (ii) subjecting said stream (SO) to distillation conditions in a distillation column, wherein the gaseous overhead stream (S1c) is enriched in propylene oxide relative to stream (SO), acetonitrile and water rich in acetonitrile relative to stream (SO) separating propylene oxide from stream (SO) by distillation comprising obtaining a liquid bottoms stream (S1a) and a side stream (S1b) comprising propylene oxide enriched in carbonyl compounds relative to stream (SO). including, the distillation column is operated at the top of the distillation column at an absolute pressure in the range from 0.1 to 2.0 bar and an internal reflux ratio in the range from 2.0 to 6.0; A method for purifying propylene oxide, wherein the distillation column has 100 or more theoretical plates, the rectifying section of the distillation column consists of 30 to 70% of the theoretical plates and the stripping section of the distillation column consists of 70-30% of the theoretical plates will be. |
