Abstract (en)

[origin: GB2332430A] A liquid phase process for preparing an olefin oxide from an olefin comprising the steps of a) contacting the olefin with oxygen or an oxygen-containing gas in a solvent having a boiling point above 130‹, b) passing the liquid product mixture comprising the olefin oxide, non-converted olefin, solvent and by-products into a first separator wherein a lower pressure is maintained than in the reaction step a) and the product mixture is divided into b1) a gaseous stream (12) containing olefin, carbon dioxide and other volatile products and b2) a liquid stream (13) containing olefin oxide, solvent, olefin, carbon dioxide and other by-products; c) passing the liquid stream (13) into a second separator wherein a lower pressure is maintained than in the first separator in step b) and the stream is divided into c1) a gaseous stream (2) containing olefin, carbon dioxide and other products and c2) a liquid stream (3) containing olefin oxide, solvent, olefin and oxygenated by-products.
