PROCESS FOR PRODUCING EPOXIDES USING AROMATIC PEROXYCARBOXYLIC ACIDS.

摘要

The invention concerns the production of epoxides from olefins using aromatic peroxycarboxylic acids. Following epoxidisation (step A), the aromatic carboxylic acids thereby produced are separated from the epoxides and catalytically hydrated (step B) to form the corresponding aromatic aldehydes which are then oxidised (step C) with oxygen or with an oxygen-containing gas mixture to form again the aromatic peroxycarboxylic acids which can be used again to produce the epoxides.
