Carbonylation of methanol to form acetic acid has been performed industrially using carbonyl complexes of cobalt or rhodium and iodide promoter in the liquid phase. Recently, it has been claimed in a few patents that nickel carbonyl or other nickel compounds are effective catalysts for the reaction at pressure as low as 30 bar. Although the reaction conditions for the rhodium catalyst are fairly mild (175/sup 0/C and 28 atm) and the product selectivity is excellent (99% based on methanol) the process has the disadvantages that the proven reserves of rhodium are quite limited and that the reaction medium is highly corrosive. It is highly desirable, therefore, to develop a vapor phase process, which is free from the corrosion problem, utilizing a base metal catalyst. The authors have already reported that nickel on active carbon exhibits an excellent catalytic activity for the carbonylations of methanol and its derivatives under moderately pressurized conditions in the presence of methyl iodide promoter. In the present work some of the catalytic features of nickel and other group 8 metals for methanol carbonylation and the role of active carbon as carrier were studied.
