- Abstract:
- The synthesis of ε-caprolactone from cyclohexanone was catalyzed by Fe-Sn-O composite oxides prepared by coprecipitation in molecular oxygen-benzaldehyde system, the optimum synthesis conditions were obtained as follows: 5 mmol cyclohexanone at room temperature and atmospheric pressure, N (benzaldehyde)∶ N (cyclohexanone) = 3∶1, Ethylene Dichloride 20 mL, oxygen flow rate 20 mL/min, reaction time 4 h; Reaction temperature 55 °C. Under this condition, the yield and selectivity of ε-caprolactone were 98.8% and 99.0% , respectively, and the structure of the catalyst was characterized by SEM and XRD.
