katalysatorharpikser of palladium or platinum loaded, makroporoese, slightly alkaline anionbyttere on the basis of tvaerbundet polystyrene, their manufacture and use

摘要

The invention relates to the use of macroporous weakly-basic anion exchangers, charged with palladium or platinum and based on crosslinked polystyrene, as catalysts for the removal of oxygen from aqueous media by catalytic reduction, a process for the preparation of these catalyst resins, and new macroporous weakly-basic anion exchangers, charged with palladium or platinum and based on crosslinked polystyrene, in which the amino groups are primary or secondary amino groups.
