铑膦均相络合物用于低级烯烃的氢甲酰化已经取得了工业规模的应用.但均相络合物存在着稳定性差、贵金属铑容易流失、催化剂回收及再生工艺复杂、腐蚀设备、污染产品以及不能用于高级烯烃的连续化羰基合成等缺点.如以不溶性功能聚合物作为配位体而制得的聚合物给合催化剂,一方面保持了络合催化的实质,另一方面又保持了多相催化剂
Rhodium phosphine homogenous complexes have been used in the industrial scale for hydroformylation of lower olefins, but the homogenous complexes have poor stability, easy loss of noble metal rhodium, complex catalyst recovery and regeneration processes, corrosion of equipment, Pollution products and can not be used for the continuous synthesis of higher olefins and other shortcomings such as polymers with insoluble functional polymer as ligands to the catalyst, on the one hand to maintain the nature of the complex catalysis, on the other hand The heterogeneous catalyst is maintained
