| titleOfInvention | METHOD TO PRODUCE ACETIC ACID |
| abstract | there is provided a method for producing acetic acid which is capable of greatly improving the life of a silver-substituted ion exchange resin (ier) to remove iodide compounds in acetic acid. with the method for producing acetic acid according to the present invention, in a carbonylation process of a methanol method, a nickel-based alloy or zirconium is used as the material of a distillation column in a dehydration step, and as concentrations of metal ions in a charge mixture of the distillation column in the dehydration step, an iron ion concentration is less than 10,000 ppb by mass, a chromium ion concentration is less than 5,000 ppb by mass, an ion concentration of nickel is less than 3,000 ppb by mass, and a concentration of molybdenum ions is less than 2,000 ppb by mass |
