Production method of tetraamminepalladium sulfate

The invention discloses a production method of tetraamminepalladium sulfate. The production method comprises the following steps of complexing ammonia water, carrying out ion exchange, neutralizing sulfuric acid, recrystallizing and purifying and the like. A synthesis method for producing the tetraamminepalladium sulfate has the advantages of simple process, few byproducts, high product purity and high conversion rate; a drying step is added into the step of complexing the ammonia water so that a condition that ammonia water which is remained on the surface of a solid participates in a reaction step of the next step and the purity of the tetraamminepalladium sulfate is influenced is avoided, and the purity of the tetraamminepalladium sulfate is further improved. 本发明公开了种硫酸四氨钯的生产方法，它包括氨水络合、离子交换、硫酸中和、重结晶提纯等步骤，本发明生产硫酸四氨钯的合成方法，工艺简单、副产品少、产品纯度高、转化率高，且本发明在氨水络合中加入了烘干步骤，这样避免固体表面残留的氨水参与到下步的反应步骤，影响硫酸四氨钯的纯度，使得硫酸四氨钯的纯度有了进步的提高。
