The invention relates to a method for preparing acrylic acid by oxidizing propylene and then acrolein, involving the recycling of gases that had not reacted by means of a partial oxidation of the propane, in parallel, at the end of the acrylic acid recovery step, then returning, to the propylene-converting reactor, a gas rich in both propane and propylene having been subjected to a second passage in the acrylic acid recovery column.
