PCT No. PCT/EP97/02522 Sec. 371 Date Nov. 19, 1998 Sec. 102(e) Date Nov. 19, 1998 PCT Filed May 16, 1997 PCT Pub. No. WO97/44299 PCT Pub. Date Nov. 27, 1997A process for the selective preparation of acetic acid from a gaseous feed comprising ethane, ethylene or mixtures thereof plus oxygen at elevated temperature, which comprises bringing the gaseous feed into contact with a catalyst comprising the elements Mo, Pd, Re, X and Y in gram atom ratios a:b:c:d:e in combination with oxygenMoaPdbRecXdYe(I)where the symbols X, Y have the following meanings: X=Cr, Mn, Nb, B, Ta, Ti, V and/or W Y=Bi, Ce, Co, Cu, Te, Fe, Li, K, Na, Rb, Be, Mg, Ca, Sr, Ba, Ni, P, Pb, Sb, Si, Sn, Tl and/or U; the indices a, b, c, d and e are the gram atom ratios of the corresponding elements, where a=1, b>0, c>0, d=0.05-2, e=0-3.
