摘要
在乙醇介质中,以RhCl3.3H2O为铑源,合成了三苯基膦氯化铑(TTC),并对合成的晶体产物进行了红外光谱(IR)及元素分析(EA),确定了产物的组成及其结构。研究了不同条件下制得的产物在苯乙烯均相加氢中的活性,得到优化的合成工艺条件。考察了合成反应温度、配体的量及后处理对产物的影响。结果表明:在70℃下,配体三苯基膦与RhCl3.3H2O的物质量比为5,乙醇介质中热过滤得到性能较优的TTC。
Tris（triphenylphosphine） chlororhodium（I）, RhCl（PPh3）, has been prepared by the interaction of an execess of triphenylphosphine with rhodium（III） chloride hydrate in ethanol. The structure of the compound was characterized by IR and EA. The effect of various parameters such as reaction temperature, amount of ligand and compound–disposal was studied on ethenylbenzene hydrogenation. The results show that TTC has high activity at 70 ℃, with ethanol as solvent and hot filtered.
