METODO PER IL RECUPERO DEL PALLADIO

Due to its ability to activate small molecules, palladium is increasingly used mainly in catalysis. For example in 2002 the world demand for Pd for the production of catalytic converters for motor vehicles was 64% of the total, equal to 3.08 million oz. Its high cost coupled with the environmental i...

description Due to its ability to activate small molecules, palladium is increasingly used mainly in catalysis. For example in 2002 the world demand for Pd for the production of catalytic converters for motor vehicles was 64% of the total, equal to 3.08 million oz. Its high cost coupled with the environmental impact of disposal of these spent materials focuses attention on its quantitative recovery by means of economically advantageous industrial processes with low environmental impact. The present invention makes available a method which is easy to apply on an industrial scale for the recovery of palladium in one single step and in mild conditions that meets the above-mentioned industrial requirements. The method uses adducts of N,N'-dialkyl-perhydrodiazepine-2,3-dithione.
