Zusammenfassung:The invention discloses a method for preparing acetic acid by iridium-based compound catalytic carbonylation. The method solves the problem that the existing acetic acid preparation method adopting iridium-based compound catalytic carbonylation utilizes a precious metal as a promoter so that a production cost is high. The method provided by the invention utilizes cyclopentadienyl manganese carbonyl as a promoter and changes the history of use of a precious metal as a promoter in the traditional technology.
