ABSTRACT:
The present invention relates to a process for manufacturing acrolein by dehydration of glycerol in the presence of molecular oxygen. The reaction is performed in the liquid phase or in the gas phase in the presence of a solid catalyst. The addition of oxygen makes it possible to obtain good glycerol conversion by inhibiting the deactivation of the catalyst and the formation of by-products.
