The invention relates to a process for manufacturing acrylic acid from propane.

According to this process, a gas mixture, which is free from molecular oxygen and comprises propane, steam as well as, optionally, an inert gas, is passed over a solid composition of formula (I)

c is between 0.006 and 1, including the end points;

d is between 0 and 3.5, including the end points; and

x is the quantity of oxygen bound to the other elements, and depends on their oxidation states,

in order to oxidize the propane according to the following redox reaction (1):
