Procedure

When the reaction is a two-stage partial oxidation of propylene to acrylic acid, some or even all of the fresh propane may also be supplied into the starting reaction gas mixture for the second stage of the partial oxidation (however, this starting reaction gas mixture is sometimes not explosive even when this qualification was actually true for the starting reaction gas mixture for the first stage of the partial oxidation). This is advantageous in particular because the undesired side reaction of propane to give propionaldehyde and/or propionic acid starts in particular from the first partial oxidation stage (propylene→acrolein) under the conditions thereof. It is also advantageous to divide a fresh propane supply substantially uniformly between the first and the second partial oxidation stage.
