【摘要】 因催化剂与产物不易分离的问题,氢甲酰化反应催化剂固载化研究受到广泛关注。本文从分子筛、二氧化硅、碳材料、金属氧化物、磁性纳米粒子、有机聚合物和离子液体这些不同负载材料的角度综述了过去十年来的相关研究结果,并对不同载体的优缺点和发展前景进行了简要分析。固载型催化剂分为3种不同的构建方式:载体与配体连接、载体与金属连接以及载体同时与配体和金属连接。第3种构建方式制备的催化剂更稳定,常在二氧化硅作为载体中使用。第一种构建方式为催化剂制备提供了多样性,在无机物和有机物作为载体中都有广泛使用,其中,含磷的有机聚合物在提供良好催化剂效果的同时,也提高了催化剂的稳定性,对未来的研究方向有一定的指导意义。更多还原

【Abstract】 Since the catalyst and the product are not easily separated, the research on the immobilization of the hydroformylation catalyst has been widely concerned. This paper reviews the results of related research over the past 10 years from the perspective of molecular sieves, silica, carbon materials, metal oxides, magnetic nanoparticles, organic polymers and ionic liquids, and the advantages and disadvantages of different carriers and their development prospects are brief analyzed. The immobilized catalyst is divided into three different construction modes: the carrier is connected to the ligand, the carrier is connected to the metal, and the carrier is simultaneously connected to the ligand and the metal. The catalyst prepared by the third construction method is more stable, and is often used with silica as a carrier.The first construction method provides versatility for catalyst preparation and is widely used with inorganic and organic materials as a carrier. Among them, the phosphorus-containing organic polymer improves the stability of the catalyst while providing a good catalyst effect, which provides a certain guiding significance for the future research direction.更多还原
