    • The invention relates to a method for producing carbonyl compounds of formula (I), in which R is a hydrogen atom or an alkyl radical with between 1 and 3 C atoms; R is a hydrogen atom or a radical of formula (II) in which R is a hydrogen atom or, together with R , an oxygen atom; R is the radical OR or, together with R , an oxygen atom; R is a hydrogen atom, an alkyl radical with between 1 and 8 C atoms or a cyclohexyl or cyclopentyl radical; and R is an alkyl radical with between 1 and 4 C atoms, a cyclohexyl or cyclopentyl radical or a radical of the formula -CH2-CHO or -CH2-CH2-O-CH2-CHO. According to said method, the carbonyl compounds are produced by gas-phase oxidation of methanol or alcohols of formula (III), in which R and R have the meaning assigned above and R is a hydrogen atom or an OR radical, and R is a hydrogen atom, an alkyl radical with between 1 and 4 C atoms, a cyclohexyl or cyclopentyl radical or a radical of the formula -CH2-CH2-OH or -CH2-CH2-O-CH2-CH2-OH, with a gas containing oxygen, in the presence of catalysts containing copper and/or silver and a phosphorus compounds which is volatile under reaction conditions, in such a quantity that the quantity of phosphorus (calculated as P) in relation to the part by weight of alcohol used is up to 20 ppm. The method is characterized in that the quantity of phosphorus is added in the catalyst bed.
