摘要
聚苯乙烯基２，２′─联吡啶与Ｒｕ３（ＣＯ）１２和Ｒｈ１２（ＣＯ）４Ｃｌ２反应，制备了担载金属羰基络合物（Ａ）和（Ｂ）．利用红外光谱进行了结构鉴定．对１─庚烯的氢甲化反应的实验结果表明，Ａ的活性低，选择性差；Ｂ的活性高，选择性好．当催化剂Ｂ０．２６克，１─庚烯１．０ｍｌ，甲苯５．０ｍｌ，压力４．０ＭＰａ（ＣＯ：Ｈ２＝１：１），温度１１０℃，反应时间２０ｈ，１─庚烯转化率达９０％以上，选择性超过９５％．进行５６０ｈ时寿命实验，Ｂ仍有很高的催化活性．
Supported metal carbonyl complexes (A) and (B) are synthesized by the reaction of poly(styryl) bipyridine with Ru3(CO)12 and Rh2(CO)4Cl2 respectively. Their structures are characterized by IR spectra. Their catalysis on hydroformylation reaction of 1-heptene is tested under the pressure of 4.0Mpa (CO: H2=1: 1). The results indicate that the activity of A is low, the selectivity is bad, B is a catalyst with high activity and good selectivity. For example, the conversion of 1-heptene exceeds 90% and with a selectivity up to 95% at 110℃.The lifetime of B lasts for 560 hours.
