• 中文摘要： 茲將銠、鉑、鎳、鈷、及銅等五種金屬分別承載於分子篩擔體上以進行甲醇羰基化反應之活性測試,所使用之分子篩包括X-及Y-型沸石、鋁磷分子篩(AlPO/sub 4/-5)以及矽鋁磷分子篩(SAPO-5)等,在所有製備的觸媒中以 Rh/NaX活性最佳,更進一步的研究發現只有帶正價未還原之銠離子才俱有活性,在Rh/NaX上加入鈷、銅、或鎳等之第二種金屬並無法改變醋酸甲酯之產率。動力學的探討發現在常壓下之反應級數對甲基碘而言是1.0,對甲醇是0.3,對一氧化碳是0.1。
• 英文摘要： Five different metals, including Rh, Pt, Ni, Co, and Cu, were tested for their activities in methanol carbonylation. These metals were impregnated separately onto molecular-sieves such as X- and Y- type zeolites as well as AlPO/sub 4/-5 and SAPO-5. Among the catalysts prepared, Rh/NaX was found to be the most active one. Further studies on Rh/NaX has shown that Rh is active in non-reducing state only. Adding a second metal such as Co, Cu or Ni to Rh/NaX does not alter the yield of methyl acetate. Kinetic study under atmospheric pressure has shown that the reaction orders are 1.0, 0.3 and 0.1 with respect to methyl iodide, methanol and carbon monoxide.
