A process for the selective production of acetic acid from a gaseous feed of ethane, ethylene, or mixtures thereof, and oxygen at a temperature of from about 75°C. to about 500°C. and a pressure of from about one atmosphere to about 75 atmospheres in the gaseous phase which comprises contacting said
A process for the selective production of acetic acid from a gaseous feed of ethane, ethylene, or mixtures thereof, and oxygen at a temperature of from about 75°C. to about 500°C. and a pressure of from about one atmosphere to about 75 atmospheres in the gaseous phase which comprises contacting said gaseous feed with a catalyst mixture containing component (A) and component (B) wherein: component (A) is at least one calcined catalyst represented by the formula: MoxVyZz in the form of its mixed oxides, wherein (x) is equal to 0.5 to 0.9; (y) is equal to 0.1 to 0.4; (z) is equal to 0 to 1; and Z, when present, is one or more of the metals Nb, Sb, Li, Sc, Na, Be, Mg, Ca, Sr, Ba, Ti, Zr, Hf, Y, Ta, Cr, Fe, Co, Ni, Ce, La, Zn, Cd, Hg, Al, Tl, Pb, As, Bi, Te, U and W; and component (B) is at least one catalyst selected from the group consisting of (i) a molecular sieve catalyst having acidic character; (ii) a palladium-containing oxides catalyst; (iii) a tungsten-phosphorus-containing oxides catalyst; or (iv) a tin-molybdenum-containing oxides catalyst.
