Abstract (en)

[origin: WO2004105938A2] The invention relates to a method for the production of acrylic acid from propane, in which a gas mixture comprising propane, water vapour and, optionally, an inert gas and/or molecular oxygen is passed over a catalyst, comprising a crystalline catalyst phase of formula (I) or (I') TeaMolVbNbcOx (I) Sba Mol VbOy (I'), associated with a crystalline catalyst phase for activating the propane.
