| 摘要 |
A novel catalyst which has a high catalytic activity, is useful for obtaining acetic acid and/or methyl acetate from methanol, and comprises an anion exchanger with its anion exchanged by the anion of an Ru-Sn heteropolynuclear compound; a process for producing acetic acid and/or methyl acetate from methanol in one-step vapor-phase reaction, wherein the catalytic activity can be retained throughout the reaction; and a process for producing acetic acid and/or methyl acetate at a high reaction rate in the presence of a highly active catalyst, for example, the above-mentioned novel catalyst. |
