Abstract:
The subject of the present invention is a process for preparing acrolein by dehydration of glycerol in the presence of a catalyst system comprising oxygen, phosphorus and at least one metal chosen from vanadium, boron or aluminium. The process is preferably carried out in the gas phase in the presence of oxygen starting from aqueous solutions of glycerol.
