A process for the production of acrylic acid by the two-stage catalytic vapour-phase oxidation of propylene with molecular oxygen, the first stage for oxidising propylene to produce mainly acrolein and the second stage for oxidising acrolein to produce mainly acrylic acid. The process comprises supplying to the first-stage reaction a raw gas containing a saturated aliphatic hydrocarbon having 1 to 5 carbon atoms in an amount in the range of 5 to 70% by volume, carbon dioxide in an amount in the range of 3 to 50% by volume, and the aliphatic hydrocarbon and the carbon dioxide in a total amount in the range of 20 to 80% by volume, the raw gas further containing steam in an amount in the range of 0.5 to 8 mol per mol of propylene.
