palladium

1.The influence of a palladium catalyst on the microwave tritium labelling reaction and dehalogenation or addition of the starting materials are discussed.

讨论了引入钯催化剂对微波氚标记,及微波氚标记过程中脱卤和加成作用影响。

2.Two different kinds of palladium complexes of nitrogen containing polymere havebeen prepared and their catalytic actions for p -nitro -methyl benzfene have been invertigeted.

制备了种不同含氮高分子-钯络合物，并研究了它们对对硝基甲苯催化活性。

3.Palladium can be separated from polyxene by the process of resolving polyxene,removing nitrate,precipitating palladium,etc.The grade of pure platinum obtained from the process is more than 99.95%.

粗铂经王水溶解,赶硝,加入丁二酮肟使大部分钯以沉淀形式与铂分,余留少量钯用溴酸钠水解法处理,可达到铂钯分,所得纯铂品位高于99.95%。

4.Some systems, like Fortress (Mirage Dental Co.) and Cerinate (Den-Mat Corp.), utilize a direct build up of a ceramic on a refractory die or on a master die swedged with palladium or platinum foil.

不同全瓷间接修复系统其材料组分与制作过程都有很大不同。牙科材料制造商在其各自系统内使用各种瓷材料与瓷填料颗粒来达到特定强度与美学效果。
