Abstract

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.

Key words： methanol carbonylation acetic acid iridium-based catalyst poisoning
