Verfahren zur selektiven Herstellung von Essigsäure

摘要

A process for the selective production of acetic acid from a gaseous supply of ethane, ethylene or mixtures thereof and oxygen at high temperature, in which the gaseous supply is brought into contact with a catalyst containing the elements Mo, Pd, Re, X and Y in the atom-gram ratios a:b:c:d:e in combination with oxygen, of formula (I) MoaPdbRecXdYe, where X is Cr, Mn, 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, Tl and/or U; the indices a, b, c, d and e stand for the atom-gram ratios of the corresponding elements, where a = 1, b > 0, c > 0, d = 0.05 to 2 and e = 0 to 3.
