(57) Abstract: A catalyst composition for the selective oxidation of ethane and / or ethylene to acetic acid is disclosed, which composition in combination with oxygen comprises the following elements: Mo a. W b. Ag c. Ir d. X e. Yf (I), where X is the element Nb and V; Y is Cr, Mn, Ta, Ti, B, Al, Ga, In, Pt, Zn, Cd, Bi, Ce, Co, Rh. , Cu, Au, Fe, Ru, Os, K, Rb, Cs, Mg, Ca, Sr, Ba, Zr, Hf, Ni, P, Pb, Sb, Si, Sn, Tl, U, Re and Pd One or more elements selected from the group; a, b, c, d, e and f are 0 <a ≦ 1, 0 ≦ b <1 and a + b = 1; 0 <(c + d) ≦ 0 .1; 0 <e ≦ 2; and 0 ≦ f ≦ 2. The catalyst composition can be used for the production of acetic acid and for the integrated production of acetic acid and / or vinyl acetate. |
