Web摘要： 采用ICP,FTIR,13CWR,31PNMR,TGA,XPS等方法,对三种水溶性铑配合物:HRh (CO) (TPPTS)3,RhCl (CO) (TPPTS)2和RhI (CO) (TPPTS)2的组成,结构和性质进行了表征.结果表明,采用新设计的方法合成的水溶性铑-膦配合物,具有以三苯基膦为配体的配合物类似的结构.它们的热稳定性很好,在水中的溶解度大,而在非极性有机溶剂中极难溶解,是良好的烯烃 … WebAbstract: Water-soluble rhodium-phoshpine complex HRhCO(TPPTS) 3 and TPPTS were supported by hydroxyapatite(HAP). The catalysts were characterized by FTIR, solid state 31 P CP-MAS NMR, SEM, ICP-OES, and N 2 adsorption-desorption measurements. The catalysts showed special isomerization performance for 1-hexene, 2-hexene and 3-hexene.
