MX_n 和 TPPTS.Ln体系催化 1-己烯氢甲酰化反应的新探索(英文)
A New Approach to Catalyzed Hydroformylation of 1-Heptene with MX_n-TPPTS.Ln System
【摘要】 在可比条件下 ,研究了新型水溶性膦配体 TPPTS.L n(TPPTS=三 (间 -磺酸基苯基 )膦 ,L n=Y,L a,Nd,Ho,Yb)分别与 Rh Cl3、Ni Cl2 、Pd Cl2 组成的体系催化 1-己烯氢甲酰化反应 .结果表明 ,TPPTS.L n- Rh Cl3(L n=Y、Ho)的催化活性优于 TPPTS.Na3- Rh Cl3体系 (1-己烯的转化率分别为 49.9%、 38.8%、 2 4.3% ) ,有意义的是 ,TPPTS.Yb- Ni Cl2 体系 (转化率 44 .5 % )亦高于 TPPTS.Na3- Rh Cl3体系的催化结果 ,且稀土离子介入水溶性膦配体后 ,使催化剂对支链醛的选择性明显提高
【Abstract】 Some new water soluble phosphine ligands TPPTS.Ln (TPPTS=tris ( m sulfonatophenyl) phosphine, Ln=Y, La ,Nd, Ho, Yb ) with RhCl 3, NiCl 2, PdCl 2 were used as the catalysts in the heterogeneous (water organic phase) hydroformylation of 1 heptene, respectively. TPPTS.Ln RhCl 3 (Ln=Y, Ho) yield exceptionally high conversion of heptene as compared with RhCl 3 TPPTS.Na 3 under the conditions used. Using NiCl 2 TPPTS.Yb satisfatory conversion of heptene is also obtained and it is much cheaper than RhCl 3, so it has great potentiality in the future industry process.
