How to remove aldehydes from acetic acid

How can the aldehydes in methanol carbonylation acetic acid be removed?
The removal of aldehydes from petrochemical products is generally achieved through the use of specialized resins for adsorption or selective hydrogenation. If the content of aldehyde impurities is low, the investment and operating costs associated with the resin adsorption process are relatively low ； If the content of aldehyde impurities is high, a selective hydrogenation process is relatively more appropriate. It is advisable to avoid choosing a resin adsorption process that involves oversized adsorption towers and large amounts of resin, as this results in plenty of waste resin waste, which is uneconomical. Moreover, frequent regeneration is required, which is also detrimental to the stable operation of production.
Resin is used quite a lot, right? If you need it, I can send you some samples for testing purposes. 13912456342
