METHOD FOR THE PRODUCTION OF NOBLE METAL OXALATE COMPLEXES

摘要

The production of precious metal oxalate complexes from precious metal precursors and oxalic acid and/or oxalic acid salts is an exothermic reaction in which heat and CO2 are formed. The temperature can rise above the decomposition point of the precious metal oxalate complexes as a result of which further CO2 is given off. For reasons of technical safety, care should therefore be taken when carrying out the reaction on an industrial scale to ensure that the product is not decomposed as a consequence of the heat generated during the reaction. According to the invention, a method for producing precious metal oxalate complexes is therefore provided, in which method the precious metal oxalate complexes corresponding to the product are added to the reaction mixture as an autocatalyst.
