    Abstract: alpha,beta-ethylenically unsaturated aldehydes and/or carboxylic acids are prepared by means of a two-stage catalytic gas-phase oxidation in which a gas mixture comprising at least an alkane or alkene having from three to six carbon atoms and oxygen is subjected to a catalytic oxidation reaction, in the first stage ( 1 ). oxygen is added to the gases produced in the first stage ( 1 ) and the resulting mixture is introduced into the second stage ( 2 ) in which it is subjected to a further catalytic oxidation reaction. In the process of the present invention, a signal which correlates with the oxygen content of the reaction gases before and/or after the addition of oxygen between the first and second stages ( 1, 2 ) is generated and the oxygen addition is regulated as a function of the signal. Also provided are an apparatus for regulating a process for preparing alpha,beta-ethylenically unsaturated aldehydes and/or carboxylic acids and an apparatus for preparing these substances using the regulating apparatus of the present invention.

    Abstract: The invention relates to a method for producing alpha , beta -ethylenically unsaturated aldehydes and/or carboxylic acids by two-step catalytic gas phase oxidation which is characterized in that in the first step (1) a gas mixture containing at least alkane or alkene having three to six carbon atoms and oxygen is subjected to a catalytic oxidation reaction. Oxygen is supplied to the gases produced in the first step (1) and the resulting mixture is added to the second step (2) in which it is subjected to another catalytic oxidation reaction. The inventive method is further characterized in that a signal is obtained that is correlated with the oxygen content of the reaction gases before and/or after addition of oxygen between the first and second step (1, 2) and in that the oxygen supply is controlled on the basis of said signal. The invention further relates to a device for controlling a method for producing alpha , beta -ethylenically unsaturated aldehydes and/or carboxylic acids and to a device for producing said substances using the inventive control device.
