Title: METHOD FOR PREPARING ACETIC ACID BY CARBONYLATION OF METHANOL
Abstract:
Provided is a method for preparing acetic acid by a carbonylation reaction of methanol, comprising passing the raw materials of methanol, carbon monoxide and water through a reaction zone loaded with acidic molecular sieve adsorbed by an organic amine as a catalyst and reacting same under certain conditions to prepare acetic acid. The method of the present invention has a high acetic acid selectivity and a good catalyst stability. The catalyst in the method of the present invention does not contain a rhodium or iridium noble metal, does not need an iodine-containing auxiliary, and does not produce a strong corrosive hydroiodic acid and the like.
