Zusammenfassung:	1497421 Acetone CHEMISCHE WERKE HULS AG 27 March 1975 [29 March 1974] 12852/75 Heading C2C [Also in Divisions B1 and C1] Acetone is prepared by contacting a gaseous mixture of 1-15% by volume of isobutyraldehyde, at least the stoichiometric amount but not more than 30% by volume of O 2 and an inert diluent, at an elevated temperature with a copper oxide catalyst with a contact time. of 0À1-10 seconds. The catalyst may be supported and may be doped with an alkali metal hydroxide. The temperature may be 150-300 C. The inert diluent may be nitrogen, with or without steam; carbon oxides from the off-gas may also be used.
