Abstract: Water-soluble rhodium-phoshpine complex HRhCO(TPPTS)3 and TPPTS were supported by hydroxyapatite(HAP). The catalysts were characterized by FTIR, solid state 31P CP-MAS NMR, SEM, ICP-OES, and N2 adsorption-desorption measurements. The catalysts showed special isomerization performance for 1-hexene, 2-hexene and 3-hexene. The results show high activity and selectivity in the hydroformylation of 1-hexene. Selectivity of 100% of aldehydes and high turnover frequency(TOF=2465 h-1) were obtained under optimum condition. The catalysts could be easily separated from organic products and reused. The mechanism of isomerization performance of the catalyst and supporting HRhCO(TPPTS)3 on HAP were discussed.
