Tetraamminepalladium(II) Sulfate application:

Tetraammonium palladium sulfate is a new type of electroplating product used for palladium plating in the electronics industry. It is mainly used for coating computer motherboards and network plugs, and manufacturing automotive catalytic crackers. Because of its high electroplating efficiency, clean and environmental protection, it has gradually replaced traditional products such as tetraammonium palladium nitrate.

Tetraamminepalladium(II) Sulfate preparation:

Traditional method: firstly activate palladium powder with hydrochloric acid, dissolve nitric acid to obtain palladium nitrate (II) solution, add sulfuric acid and heat to volatilize part of the nitro group to obtain a mixture of palladium sulfate (II) and palladium nitrate (II), add ammonia A solution containing tetraammine palladium (II) sulfate is obtained, and excess ammonia water is added to obtain tetraammine palladium (II) sulfate crystals.
Ion exchange synthesis method: This synthesis method uses PdCl2 as the starting material, ammonia complexes to generate Pd(NH3)4Cl2, and then replaces Cl- with OH- through ion exchange to generate Pd(NH3)4(OH)2, and finally with sulfuric acid The reaction produces Pd(NH3)4(SO4)2, which is purified by recrystallization to obtain the final product. The synthesis method firstly, the raw materials, intermediate products, and the medium in which the product is located are relatively simple, which is beneficial to control the impurity content and improve the product quality; secondly, the reaction is more thorough, and the target product yield is high; thirdly, the synthesis process is green and environmentally friendly. Environmental pressure is small. In short, the ion exchange synthesis process is simple to operate, pollution-free, and has high purity.
