The rhodium-catalyzed methanol carbonylation process to acetic acid, developed by Monsanto, was an important contribution to organic chemical processing. Prior to the development of Monsanto's technology, carbonylation of methanol was practiced by BASF in a higher pressure, lower selectivity, cobalt-catalyzed process. The cobalt catalyst required a system pressure of 7500 to 10,000 psig. This process was based on W. Reppe's discovery that the ''iron group'' can catalyze the carbonylation of methanol in the presence of a limited amount of halide. The rhodium process is highly selective and operates under mild reaction pressure, 500 to 1000 psig. However, because of the high price of rhodium, an expensive and elaborate rhodium recovery section is an integrated part of the new acetic acid plant. This is a big financial burden especially in a scaled down plant because the same size of recovery section has to be used in the small plant. It is evident that the next improvement in this technology is to develop a process catalyzed by a less expensive but as selective and as active catalyst as rhodium.
