1308380 Propylene oxide, isopropanol and acetone BADISCHE ANILIN- & SODAFABRIK AG 22 July 1970 [23 July 1969] 35465/70 Heading'C2C Propylene oxide, isopropanol and acetone are prepared continuously by reacting propylene and isobutyraldehyde with oxygen or a gas containing molecular oxygen in the liquid phase at elevated temperature and superatmospheric pressure, the reaction being carried out in the presence of 1-25% by weight of propane with respect to propylene and 90-99À5% of the recovered mixture of propylene and propane being returned to the reaction without separation of the propane. A catalyst may be used, e.g. a compound of a transition element, the cobalt and manganese salts of fatty acids being preferred. Preferably the reaction is carried out in an inert solvent, e.g. benzene, chlorobenzene, ethyl acetate, acetone and acetonitrile.
