Conversion and Selectivity in Hydroformylation of Hex-1-en with Silica-Gel-, Silica-Alumina-Gel and Alumina-Oxide- Supported Dicobalt Octacarbonyl and Cyclopentadienylcobalt DicarbonylThe catalytic influence of silica-gel-, silica-alumina-gel- and alumina-oxide-supported Co2(CO)8 and CpCo(CO)2 on the conversion and selectivity in hydroformylation of hex-1-en has been studied at 353 K under 120 bar syngas pressure in acetonitrile. The support systems were prepared by impregnation of SiO2 (Grace), SiO2/4% Al2O3 (Kali Chemie), SiO2/11% Al2O3 (Kali Chemie) and Al2O3 (Kali Chemie) using Co2(CO)8 and CpCo(CO)2 solutions in pentane, dichlormethane and 2-chlorpropane.The results are discussed with regard to some measured relevant support characteristics. The turn over numbers especially those of silica-gel- and silica-alumina-gel supported Co2(CO)8 and CpCo(CO)2 show positive effects in relation to a heterogeneous catalytic process within these reactions.
