【摘要】：以铁次卟啉二甲酯(Fe Cl DPDME)为模型催化剂,在无任何外加溶剂及助剂的条件下,催化氧气氧化α-蒎烯,探讨了反应温度、反应时间、催化剂质量分数以及氧气流速等工艺条件对反应的影响,并对Fe卟啉催化烃类分子氧反应机理进行初步探讨。研究结果表明:氧化主要发生在α-蒎烯双键和烯丙位碳氢键,当反应温度为80℃、反应时间为6 h、催化剂质量分数为50 mg/kg、氧气流速为60 m L/min时,α-蒎烯转化率及主要氧化产物的选择性更高,分别达到17.9%和86.7%。
[Abstract]:The oxidation of 伪 -pinene by oxygen was studied by using FeCl DPDME-FeCl DPDMEas as model catalyst and without any additional solvent and auxiliary agent. The reaction temperature and reaction time were discussed.The effects of catalyst mass fraction and oxygen flow rate on the reaction were investigated. The mechanism of catalytic reaction of hydrocarbon molecular oxygen catalyzed by Fe porphyrin was discussed.The results show that the oxidation occurs mainly in 伪 -pinene double bond and allyl hydrocarbon bond, and the reaction temperature is 80 鈩，
