Zusammenfassung:	325The present invention relates to the manufacture of bioresourced acrolein and bioresourced acrylic acid from glycerol as starting material and more particularly comes within the scope of a process for the manufacture of acrolein and acrylic acid according to which the reaction for the dehydration of glycerol to give acrolein is carried out and10 the organic compounds which are heavier than water liable to be present in the various streams of the process are removed, so as to obtain a stream which can be recycled to the dehydration stage without accumulation of heavy impurities, while minimizing the consumption of water and the discharge of polluted aqueous streams.
