Abstract

A highly dispersed cobalt catalyst for hydroformylation of 1hexene was developed using macroporous silica pore diameter 837 nm as support The effects of support pretreatment on the properties and catalytic activities of the obtained catalysts were investigated The results indicated that slurry impregnation SI method could significantly enhance the interaction between support and cobalt precursors leading to the formation of small cobalt particles Moreover this interaction would increase with the pretreating temperature or the number of hydroxyl groups in pretreating solvent Due to the small cobalt particles and high diffusion rate of reactants and products in the macropore the highly dispersed Co/Q100 PTO SI333 catalyst exhibited 11 times higher heptanal yield and much higher n/i ratio than the conventional Co/SiO2 EG catalyst which was prepared on mesoporous silica which contained similar cobalt particle sizeThis work was supported by National Natural Science Foundation of P R China No 91334206 21606011 Ministry of Education of P R China NCET130653 National “863” program of P R China No 2013AA031702 Innovation and Promotion Project of Beijing University of Chemical Technology No JC1505 BUCT Fund for Disciplines Construction and Development No XK1505 and China Postdoctoral Science Foundation 2016M591051
