| 中文摘要: |
| 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。 |
| 英文摘要: |
| [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. |
