ABSTRACT:
The present invention relates to a process for producing a highly purified acetic acid characterized in that in the process for producing acetic acid comprising the step of continuously reacting methanol and/or an aqueous solution of methyl acetate with carbon monoxide in a reactor, a treatment is conducted to limit the concentration of unsaturated compounds in crude acetic acid obtained in the process to 5 ppm or lower, and the resultant crude acetic acid is ozonized. The present invention also relates to a process for producing a highly purified acetic acid, characterized by comprising the step of continuously reacting methanol and/or an aqueous solution of methyl acetate with carbon monoxide in a reactor while maintaining the concentration of acetaldehyde in a reaction fluid in the reactor at 1500 ppm or lower.
