A catalyst composition for the selective oxidation of ethane and/or ethylene to acetic acid which composition comprises in combination with oxygen the elements: Moa.Wb.Agc.Ird.Xe.Zf (I) wherein X is the elements Nb and V; Z is one or more elements selected from the group consisting of: Cr, Mn, 'á, '_, é, 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; a, b, c, d, e and f represent the gram atom ratios of the elements such that 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 may be used in the production of acetic acid and in an integrated process for the production of acetic acid and/or vinyl acetate. |
