摘要
采用一种全新的方法—离子交换法,以二氯四氨合铂(Ⅱ)和二氯四氨合钯(Ⅱ)为原料,水为溶剂,制备铂、钯的重要催化前驱体化合物—硝酸四氨合铂(Ⅱ)和硝酸四氨合钯(Ⅱ)。通过元素分析、红外光谱、质谱、核磁共振表征其化学结构。方法的产率>90%,产品纯度>99.0%(以金属铂、钯计),适合于批量生产要求。
[Pt（NH3）4]（NO3）2 and [Pd（NH3）4]（NO3）2 are two important precursors for platinum-and palladium-based heterogeneous catalysts, as well as intermediates for other platinum and palladium compounds. An ion exchange technique was employed to synthesize [M（NH3）4]（NO3）2（M=Pt or Pd） with a yield of more than 90% from [M（NH3）4]Cl2 as the starting materials. Their chemical structures were characterized by elemental analysis, MS, IR and NMR. This synthetic method is very effective and cost-saving and can be employed in industrial production.
