Definitions
- the invention relates to the technical field of catalysts, in particular to a hydroformylation catalyst and its preparation method and application.
- the hydroformylation of olefins is one of the main methods for preparing aldehydes. Hydroformylation was first discovered by O. Roelen in 1938 at Ruhrchemie Chemical Company in Germany. The first generation of hydroformylation catalytic process uses cobalt carbonyl as a catalyst. Co 2 (CO) 8 is first dissolved in the reaction solution. Under the reaction conditions, the formed HCo(CO) 4 is considered to be the active species in the reaction. Species are easily decomposed to produce CO, and need to be stable under higher CO pressure.
- the second-generation hydroformylation catalytic process uses phosphorus ligands to improve the stability of catalytically active species, which can effectively reduce the pressure required for the reaction and increase the proportion of normal aldehydes.
- phosphorus ligands will cause a decrease in catalyst activity and accelerate the hydrogenation reaction of olefins and product aldehydes, resulting in a decrease in aldehyde selectivity.
- the third-generation hydroformylation catalytic process is an oil-soluble rhodium ligand complex catalyst with metal Rh as the active center.
- This type of catalyst can greatly improve the reaction efficiency.
- the Rh catalyst modified by triphenylphosphine is used. Mild, high normal aldehyde selectivity, olefin hydrogenation and other side reactions are greatly reduced, but its disadvantage is that the product and the catalyst are in a homogeneous liquid phase, the separation of the product and the catalyst and the recovery of the catalyst are difficult, and the distillation product is separated Catalysts often lead to problems such as product polymerization, catalyst decomposition and deactivation.
- the fourth-generation hydroformylation catalytic process uses a water-soluble phosphorus ligand and an oil-water two-phase reaction system.
- the catalyst exists in the water phase and the product aldehyde is in the oil phase. After the reaction, the catalyst and the product can be effectively separated by standing still. Due to the low mass transfer efficiency of the two-phase reaction, which affects the catalytic effect, it is necessary to add a phase transfer agent, but the addition of the phase transfer agent will cause emulsification and increase the difficulty of phase separation.

本发明涉及催化剂技术领域,特别是涉及一种氢甲酰化催化剂及其制备方法和应用。
烯烃的氢甲酰化反应是制备醛类物质的主要方法之一。氢甲酰化最早由O.Roelen于1938年在德国Ruhrchemie化学公司发现。第一代氢甲酰化催化工艺以羰基钴为催化剂,Co
2(CO)
8首先溶解在反应液中,在反应条件下,形成的HCo(CO)
4被认为是反应的活性物种,但是该物种极易分解产生CO,需要在较高的CO压力下才能得以稳定存在。
第二代氢甲酰化催化工艺采用磷配体提升催化活性物种的稳定性,可有效降低反应所需压力,提高正构醛的比例。但磷配体会导致催化剂活性的下降,而且会加速烯烃及产物醛的加氢反应,造成醛选择性的下降。
第三代氢甲酰化催化工艺是以金属Rh为活性中心的油溶性铑配体络合物催化剂,该类催化剂可大大提升反应效率,如采用三苯基膦改性的Rh催化剂,反应条件温和,正构醛选择性高,烯烃加氢等副反应都极大降低,但其缺点是产物与催化剂是处在均一的液相中,产物与催化剂的分离以及催化剂的回收困难,蒸馏产物分离催化剂常会导致产物聚合、催化剂分解失活等问题。
第四代氢甲酰化催化工艺采用水溶性的磷配体和油-水两相反应体系,催化剂存在于水相,产物醛位于油相,反应后静置即可有效分离催化剂和产物,但由于两相反应传质效率较低,影响催化效果,需要加入相转移剂,但相转移剂的加入会导致乳化现象而增加相分离难度。
因此,如何获得活性高同时还能够分离回收的催化剂是我们亟待解决的问题。
