Abstract:Porous γ-Al2O3 was prepared using peach gum and aluminium ammonium sulfate as raw materials. Its surface area,pore volume, pore size and pore-size distribution can be controlled by adjusting the ratios of raw materials used and the calcination parameters. A novel catalyst, sulfonated polyphenylene sulfide rhodium complex, was distributed on the porous γ-Al2O3 with high specific surface area. Hydroformylation of α,ω-hendecene methyl ester, which occurred at 80℃ in different solvents and under different pressures, was systematically studied. It was revealed that α,ω- lauraldehyde ester was a main reaction product without the presence of hydrogenated by -products. Normal/isomeric ratio and catalytic process were analyzed from the aspects of electron factor, steric hindrance, and so on.
Keywords:gamma-alumina, sulfonated polyphenylene sulfide rhodium complex, hendecene methyl ester, hydroformylation
