一种从羰基化反应制备高纯度乙酸的方法,其中进行羰基化反应,同时在反应介质中保持低的碘乙烷含量。可以通过从反应介质中除去乙醛和/或通过调节A)反应器中的氢分压,B)反应介质的乙酸甲酯浓度和/或C)反应介质的碘甲烷浓度中的至
A process for producing highly pure acetic acid from a carbonylation reaction wherein a carbonylation reaction is carried out while maintaining a low content of ethyl iodide in the reaction medium. The reaction can be carried out by removing acetaldehyde from the reaction medium and / or by adjusting A) the hydrogen partial pressure in the reactor, B) the methyl acetate concentration of the reaction medium and / or C) the methyl iodide concentration in the reaction medium
