摘要：A process for the production of acetic acid which process comprisescarbonylating methanol and/or a reactive derivative thereof in a liquid reactioncomposition in which there exists in equilibrium, at least a first soluble catalytic speciesand a second soluble catalytic species, wherein the first catalytic species is the leastcatalytically active or promotionally active of the species existing in the equilibrium,comprises determining (i) the concentration of the first catalytic species and/or (ii) theratio of the concentration of the first catalytic species to the concentration of the secondcatalytic species in equilibrium therewith, present in the liquid reaction compositionand/or a present in a liquid fraction in a separation step and maintaining (i) and/or (ii)below a pre-determined value, preferably by adjusting the concentration of at least thefirst catalytic species present in the liquid reaction composition and/or liquid fraction.
