摘要：

SBA-15 zeolite supported amorphous ternary Co-Ni-B was prepared by the ultrasonic-assisted impregnation method for catalyzing the hydroformylation of 1-octene to nonanal. Supporting on SBA-15 increased the dispersion of nano amorphous Co-Ni-B. The crystallization temperature of amorphous Co-Ni-B was elevated by 280 ℃ that improves the thermal stability of Co-Ni-B. Using Co-Ni-B/SBA-15 with Co loading of 17.22% and the ratio of n (Ni)/ n (Co) of 0.157 and n (B)/ n (Co + Ni) of 0.434, the conversion of 1-octene and the selectivity of nonanal reached 100% and 91.24%, respectively, in the hydroformylation reaction at 120 ℃ and 5 MPa. The selectivity of side-product was reduced by 1 time compared with that of Co-Ni-B. The Co-Ni-B/SBA-15 is stable after repeated used for 5 times. © 2021, Science Press. All right reserved.
