May I ask if palladium on carbon can be soaked in ETOH?

May I ask if the catalyst used for hydrogenation can be soaked in ETOH, and will it affect its activity? Which compounds easily cause the deactivation of palladium on carbon? Thank you for your advice! !

It describes a method for reactivating palladium-carbon catalysts; through appropriate treatment of the deactivated catalysts, a certain amount of palladium is loaded back onto them to create reactivated palladium-carbon catalysts that can be used again in TA hydrogenation purification processes. The method includes: extracting and washing the deactivated palladium-carbon catalyst using supercritical CO2 ； The deactivated palladium-carbon catalyst was placed in nitric acid, boiled and dried, and then placed in an ammonia solution ； Add PdCI again : ； This is the catalyst precursor obtained after filtration ； The catalyst precursor is reduced with NaOH and formaldehyde, dried to yield a reactivated palladium/carbon catalyst. http://d.namipan.com/d/586c080e8c2adc63c56e96ba375f633e80587aafe55e0500 1# samop123
