Synthesis method of trans-dichlorodiammine palladium (II)

The invention relates to the field of synthesis of inorganic compounds, in particular to a synthesis method of trans-Dichlorodiammine palladium (II). The method includes the following steps: dissolving a disodium tetrachloropalladate solution in anhydrous ethanol, and then introducing high-purity ammonia gas for reaction to generate trans-Dichlorodiammine palladium (II) through one step; leaving the solution system to stand after the reaction for aging, and then filtering; washing and drying the precipitate to obtain trans-Dichlorodiammine palladium (II). The synthesis method provided by the invention uses disodium tetrachloropalladate as a starting material and adopts a one-step synthesis method, so that the process is simple; high-purity ammonia gas is adopted, and precise control of the reaction system is achieved, so that the product purity is improved; an ultrasonic reactor is adopted, and the reaction efficiency is improved, so that the product yield reaches 99.5% or above; the product obtained through the reaction is uniform in particle size distribution, fine and loose in particles, and easy to wash and filter, so that the product purity is as high as 99.9% or above.
