Abstract
A process for the continuous production of either acrolein or acrylic acid as the target product from propene comprising a catalyzed gas phase partial oxidation of propene to yield a product gas containing the target product, transferring the target product in a separating zone from the product gas into the liquid phase and conducting out of the separating zone a stream of residual gas the major portion of which is returned into the partial oxidation and the remaining portion of said stream is purged from the process as off-gas from which synthesis gas can be produced or which can be added to synthesis gas produced otherwise.
