Acrylic acid is produced by dehydrating glycerol over a first mixed metal oxide catalyst in the presence of oxygen and water to produce acrolein, and then oxidizing the acrolein over a second mixed metal oxide catalyst in the presence of oxygen and water to produce the acrylic acid. The first mixed metal oxide catalyst comprises oxides of tungsten and zirconium. The second mixed metal oxide catalyst comprises a solid catalyst having the empirical formula A.sub.aV.sub.bN.sub.cX.sub.dO.sub.e wherein A is at least one element selected from the group consisting of Mo and W, N is at least one element selected from the group consisting of Te and Se, and X is at least one element selected from the group consisting of Nb, Ta, Ti, Al, Zr, Cr, Mn, Fe, Ru, Co, Rh, Ni, Pt, Bi, B, In, Ce, As, Ge, Sn, Li, Na, K, Rb, Cs, Fr, Be, Mg, Ca, Sr, Ba, Ra, Hf, Pb, P, Pm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Lu, Au, Ag, Re, Pr, Zn, Ga, Pd, Ir, Nd, Y, Sm, Tb, Br, Cu, Sc, CI, F and I. A, V, N and X are present in such amounts that the atomic ratio of A:V:N:X is a:b:c:d wherein a=1, b=0.1 to 2, c=0.1 to 1, d=0.01 to 1 and e is dependent on the oxidation state of the other elements in the second mixed metal oxide catalyst.
