| 英文摘要 | The carbonylation of methyl acetate to acetic anhydride catalyzed by a partially quaternized poly(4-vinylpyridine) bound rhodium complex with methyl iodide as the promoter has been investigated. The reaction was verified to be first order with respect to both rhodium and methyl iodide in the presence of lithium acetate and provided that the partial pressure of carbon monoxide was above 1.5 MPa. The oxidative addition of methyl iodide to the active rhodium species and the subsequent reaction of acetyl iodide with methyl acetate to produce acetic anhydride were discovered to be the two rate-determining steps, of which the latter depended on the concentration of lithium acetate. A possible reaction mechanism was suggested. The activation parameters were determined and re-denied that a higher catalytic activity of the partially quaternized poly(4-vinylpyridine) bound rhodium complex for the carbonylation of methyl acetate to acetic anhydride was essentially due to the reduction of activation energy.
