Abstract:
A single stage catalytic process for direct conversion of propane to acrylic acid and acrolein by means of propane oxidation comprising oxidizing propane in a reaction mixture comprising (i) propane or propane/propylene and (ii) oxygen or a compound capable of providing oxygen in a reaction zone in the presence of a catalyst system containing a catalyst composition comprising Mo.sub.d V.sub.b Ga.sub.c Pd.sub.d Nb.sub.e X.sub.fwherein:X=at least one element selected from La, Te, Ge, Zn, Si, In and W;a is 1;b is 0.01 to 0.9;c is >0 to 0.2;d is 0.0000001 to 0.2;e is >0 to 0.2;f is >0 to 0.5; andwherein the numerical values of a, b, e, d, e and f represent the relative gram-atom ratios of the elements Mo, V, Ga, Pd, Nb and X, respectively, in the catalyst and the elements are present in the combination with oxygen.
