摘　　要：以乙酰丙酮二羰基铑为金属前驱体,新型双膦共聚物CPOL-BP1&PPh_(3)为载体制备Rh/CPOL-BP1&PPh_(3)催化剂。采用TEM、BET、XPS、FT-IR等方法表征。结果表明,该催化剂具有较大的比表面积及丰富的微孔-介孔结构,Rh原子以(20~40)nm的间距分布在载体上。最佳反应条件为反应压力1.0 MPa,反应温度100℃,乙烯流量1 L·h^(-1),乙烯转化率可达95%;在400 h的长周期实验中丙醛收率基本保持不变,催化剂稳定性良好。Rh/CPOL-BP1&PPh_(3) catalyst was prepared using acetyl acetone dicarbonyl rhodium as metal precursor,and new type of bisphosphine copolymer CPOL-BP1&PPh_(3) as support.The catalyst was characterized by TEM,BET,XPS and FT-IR.The results showed that the catalyst had a large specific surface area and abundant microporous mesoporous structure.Rh atoms were distributed on the support at(20~40)nm spacing.The optimum reaction conditions were reaction pressure 1.0 MPa,reaction temperature 100℃,ethylene flow rate 1 L·h^(-1),and ethylene conversion up to 95%.The yield of propanal remained unchanged after 400 h of TOS,and the catalyst had good stability.
