摘要:
在分子氧-苯甲醛体系,由共沉淀法制备的Fe-Sn-O复合氧化物作为催化剂,催化分子氧化环己酮合成ε-己内酯,通过单因素实验,得到适宜的合成条件:常温常压下,以环己酮用量为5 mmol计;n(苯甲醛)∶n(环己酮)=3∶1;1,2-二氯乙烷20 mL;氧气流速20 mL/min;反应时间4h;反应温度55℃.该条件下,ε-己内酯收率达到98.8％,选择性达到99.0％;采用SEM、XRD等对催化剂的结构进行表征;催化剂重复使用5次仍保持较高活性.
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.
