| titleOfInvention | Method for producing acetic acid |
| abstract | The invention provides a method for producing acetic acid, which can greatly improve the life of a silver-substituted ion exchange resin (IER) for removing organic iodine compounds in acetic acid.n n n In the acetic acid production method of the present invention, in the methanol carbonylation process, the material of the distillation tower in the dehydration step is nickel-based alloy or zirconium, and the concentration of metal ions in the addition liquid of the distillation tower in the dehydration step is iron Ions are less than 10,000 mass ppb, chromium ions are less than 5000 mass ppb, nickel ions are less than 3000 mass ppb, and molybdenum ions are less than 2000 mass ppb. |
