摘要
用Ｘ射线光电子能谱（ＸＰＳ）的分析方法，对非离子水溶性膦铑配合物ＲｈＣｌ３／ＴＰＰＰ的组成、结构进行表征。并且用曲线拟合分峰技术对配体ＴＰＰＰ、配合物ＲｈＣｌ３／ＴＰＰＰ催化剂中各元素的峰进行数据处理。结果表明配体ＴＰＰＰ与配合物ＲｈＣｌ３／ＴＰＰＰ比较，配合物中存在Ｒｈ－ＣＯ配位和Ｒｈ－Ｐ配位，通过ＸＰＳ分析测试结果推断，原位合成的ＲｈＣｌ３／ＴＰＰＰ配合物催化剂其结构表示为ＣｌＲｈ（ＣＯ）ｎ（ＴＰＰＰ）ｍ。
The composition of nonionic water-soluble phosphine rhodium complexes RhCl 3/TPPP has been characterized,by using X-ray photoelectron spectroscopy.Every elemental peak in the ligand TPPP and the complexes RhCl 3/TPPP catalyst have been measured mathematically by means of the curve fitting technique.It was found that the ligand Rh-CO and Rh-P present in the complexes as compared with the ligand TPPP.The synthesized RhCl 3/TPPP complex formula ClRh(CO) n(TPPP) m was also deduced.
