Abstract: The invention relates to a method for producing carbonyl compounds of formula (I), in which R1 is a hydrogen atom or alkyl radical with between 1 and 3 C atoms; R2 is a hydrogen atom or a radical of formula (II), in which R3 is a hydrogen atom or, together with R4, an oxygen atom; R4 is the radical OR6 or, together with R3, an oxygen atom; R5 is a hydrogen atom, an alkyl radical with between 1 and 8 C atoms or a cyclohexyl or cyclopentyl radical; and R6 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 R1 and R5 have the meaning assigned above and R7 is a hydrogen atom or an OR8 radical, and R8 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 compound which is volatile under reaction conditions in such a quantity that the amount of phosphorus (calculated as P), in relation to the part by weight of alcohol used, is up to 20 ppm. Said method is characterized in that the quantity of phosphorus is added in at least two parts: a) the first part is added with the gaseous starting mixture before the catalyst bed, and b) at least one other part is added in the catalyst bed.

Abstract: In continuous gas phase oxidn. of C3H6 to acrolein (I) and/or acrylic acid (II) with heterogeneous catalyst in an oxidn. reactor, the charge gas mixt. (III) contains only inert diluent gas(es) (IIIA) in addn. to C3H6 and O2 and (pt. of) (IIIA) is sepd. from the prodn. gas mixt. and recycled to the oxidn. reactor. The novelty is that (IIIA) consists of over 85 vol. % 1-5C satd. hydrocarbon(s).

Abstract: The invention concerns a method of removing nitrogen oxides from a gas flow. The gas flow is guided: (A) through a stage in which the nitrogen oxides, apart from N2O, are absorbed in an absorption agent, or the nitrogen oxides, apart from N2O, are reacted with an absorption agent at a pressure of between 1.5 and 20 bar; and (B) through a stage for reducing the N2O content, preferably using the pressure level prevailing in step (A). The invention further concerns a device for carrying out this method and the use thereof.

Abstract: Prodn. of acrolein (I) and/or acrylic acid (II) from C3H8 involves (A) gas phase partial dehydrogenation of C3H8 to C3H6, using heterogeneous catalyst; (B) using the prod. gas mixt. of C3H6 and unreacted C3H8 for charging an oxidn. reactor, in which C3H6 is converted to (I) and/or (II) by gas phase selective partial oxidn. with pure O2 using heterogeneous catalyst; and (C) separating the prod. from the prod. gas stream and recycling at least the unreacted C3H8 from stage (B) to stage (A). The novelty is that, before entering stage (B), constituents other than C3H8 and C3H6, at least H2 and steam, are removed from the prod. gas mixt. from stage (A). Pref. all constituents except C3H8 and C3H6 are removed after stage (A). Stage (B) is carried out in 2 consecutive reactors charged with multi-metal oxide catalysts, the first of Mo-Bi-Fe and the second of Mo-V. The prod. gas mixt. from the first oxidn. reactor is passed directly into the second; and the vol. ratio of organic cpd. for partial oxidn. (C3H6 or (II)) to O2 is 1:(1-3) in both reactors.

Abstract: The invention relates to a method for the heterogeneously catalysed partial gas phase oxidation of acrolein to form acrylic acid, whereby the initial mixture of reaction gas is oxidised on a fixed-bed catalyst bed which consists of at least two fixed-bed catalyst bed zones and is arranged in two successive temperature zones A and B. The transition from temperature zone A to temperature zone B does not coincide with a transition from a fixed-bed catalyst bed zone to another fixed-bed catalyst bed zone.
