The process of methanol carbonylation to produce acetic acid is a significant industrial chemical reaction. In contrast to rhodium-based catalysts, iridium-based catalysts offer benefits including in lower cost, reducing water content during production, and decreasing formation of by-product propionic acid. Nevertheless, challenges such as the catalyst's susceptibility to impurity ions and the high expense associated with catalyst separation remain prevalent. The reaction mechanism of traditional iridium-based catalysts in the methanol carbonylation process for the production of acetic acid were summarized. And it also was reviewed that the factors contributing to the deactivation of iridium-based catalysts and discusses the advancements in the design and synthesis of novel iridium-based catalysts. The objective is to offer valuable theoretical insights and practical recommendations for enhancing and refining the methanol carbonylation process for acetic acid production.
