The invention concerns a method for producing acrylic acid from propane in the absence of molecular oxygen. Said method is characterized in that it consists in passing a gas mixture free of molecular oxygen and comprising propane, water vapour, as well as, optionally, an inert gas, over a catalyst including molybdenum, vanadium, tellurium, oxygen and at least another element X selected among niobium, tantalum, tungsten, titanium, aluminium, zirconium, chromium, manganese, iron, ruthenium, cobalt, rhodium, nickel, palladium, platinum, antimony, bismuth, boron, indium and cerium, and on a co-catalyst of formula (II): Mo<SUB>1</SUB>Bi<SUB>a'</SUB>Fe<SUB>b'</SUB>Co<SUB>c'</SUB>Ni<SUB>d'</SUB>K<SUB>e'</SUB>Sb<SUB>f'</SUB>Ti<SUB>g'</SUB>Si<SUB>h'</SUB>Ca<SUB>i'</SUB>Nb<SUB>j'</SUB>Te<SUB>k'</SUB>Pb<SUB>l'</SUB>W<SUB>m'</SUB>Cu<SUB>n'</SUB>. The invention also concerns a solid catalytic composition comprising said catalyst and co-catalyst and the use of said composition for producing acrylic acid from propane.
