    摘要: The invention relates to a method for producing acetic acid from ethane and oxygen on a fixed bed catalyst, characterized in that a reactor cascade with an oxygen feed between the reactor levels is used. This particularly advantageous method provides high conversion rates, highly pure acetic acid and low ethylene and carbon monoxide formation.
