Process for the selective production of acetic acid from a gaseous feed and oxygen

摘要

The process for the selective preparation of acetic acid from a gaseous feed and oxygen at elevated temperatures comprises bringing the gaseous feed into contact with a catalyst of formula I MoaPdbRecXdYe comprising Mo, Pd, Re, X and Y in gram atom ratios a:b:c:d:e in combination with oxygen wherein: X is Cr, Mn, Nb, B, Ta, Ti, V and/or W; Y is Bi, Ce, Co, Cu, Te, Fe, Li, K, Na, Rb, Be, Mg, Ca, Sr, Ba, Ni, P, Pb, Sb, Si, Sn, Ti and/or U and a is 1, b>0, c>0, d is 0.05-2 and e is 0-3. The gaseous feed comprises ethane, ethylene or mixtures thereof.
