Method for producing acetic acid |
abstract |
A process for the production of acetic acid is disclosed wherein the water concentration is controlled in a side stream between two columns. The hydrogen iodide concentration in the side stream is controlled to be less than or equal to 50 wppm by controlling the water concentration by liquid light phase recirculation. |
