本文用离子键键合法和共价键键合法合成了五种聚合物胺基膦配体键联的铑络合物催化剂,它们对二异丁烯的氢甲酰化反应有良好的催化活性和成醛选择性。用共价键键合法制得的聚合物催化剂有着良好的重复使用性能,反应后溶液中铑含量分析结果表明催化剂只有轻微的铑脱落。
In this paper, five kinds of polymeric aminophosphine ligand-linked rhodium complex catalysts were synthesized by ionic bonding and covalent bonding. They have good catalytic activity for the hydroformylation of diisobutylene and formation of aldehydes Selective. The polymer catalyst prepared by the covalent bond method has good reusability. The rhodium content in the solution after the reaction shows that the catalyst has only a slight rhodium loss.
