Abstract:
1. A process for oxidizing at least one aldehyde with oxygen, which comprises the following steps: (a) adding the at least one aldehyde as a liquid and an oxygenous gas stream to a first reaction stage to form a reaction mixture, at least some of the oxygen reacting with the organic compound to form a reaction product, (b) adding the reaction mixture from the first reaction stage to an adiabatically operated reaction stage in which the unconverted aldehyde reacts further at least partly to give the product, wherein the reaction mixture from the first reaction stage, before being added to the adiabatically operated reaction stage, is sent to at least one further reaction stage, and wherein the first reaction stage and the at least further reaction stage are operated at essentially the same temperature, or are operated such that the temperature increases from reaction stage to reaction stage, and wherein oxygenous gas is supplied to the at least one further reaction stage.
