Abstract：The low-pressure carbonylation synthesis of acetic acid from methanol has become the most mature production technology at present. In the market situation of overall excess acetic acid production capacity, reducing production costs will be particularly important. Among them, the rhodium triiodide catalyst accounts for a large part of the production cost. The reaction mechanism of rhodium triiodide in the low-pressure carbonylation synthesis of acetic acid from methanol was analyzes, and the factors affecting the dissolution rate of rhodium triiodide to determine the optimal process parameters were explored. A new process for improving the dissolution rate of rhodium triiodide was explored, which is simple to operate and has a high dissolution rate, which can greatly save the start-up time of the acetic acid production unit, the load lifting speed of the acetic acid plant has strong guiding significance for the improvement of acetic acid production technology was Effectively improving.
