PALLADIUM NITRATE SOLUTION AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a palladium nitrate solution which, when applied to a catalyst or the like, can reduce the corrosiveness of the resultant product.;SOLUTION: The palladium nitrate solution has a chlorine content of ≤100 ppm relative to the palladium content. This palladium nitrate solution is produced by packing powdery palladium into a column to form a powder layer, passing nitric acid through the powder layer to react the powdery palladium with the nitric acid, and recovering palladium nitrate formed by the reaction.;COPYRIGHT: (C)2010,JPO&INPIT
