研究了金属卟啉仿生催化环戊烷选择氧化的反应。结果表明,反应时间、温度、压力、催化剂浓度和类型对反应具有明显的影响。其中,反应温度和压力对反应总选择性影响最大,反应适宜的条件是温度145℃,压力2.5 MPa,时间4 h,金属卟啉用量14×10~(-4)mol%,搅拌速率800 r/min。不同中心金属离子的金属卟啉催化环戊烷氧化的活性顺序为Fe>Co>Mn。其中,催化效果较好的催化剂为T(o-NO_2)PPFeCl,主产物戊二酸、环戊醇和环戊酮的总收率和总选择性分别为6.2%和86.1%。
The selective oxidation of cyclopentane with metalloporphyrin was studied. The results show that the reaction time, temperature, pressure, catalyst concentration and type have a significant effect on the reaction. Among them, the reaction temperature and pressure had the greatest effect on the total selectivity of the reaction. The reaction conditions were as follows: temperature 145 ℃, pressure 2.5 MPa, time 4 h, the amount of metalloporphyrin 14 × 10 ~ (-4) mol%, stirring rate 800 r / min. The activity order of cyclopentane oxidation catalyzed by metalloporphyrin with different central metal ions is Fe> Co> Mn. Among them, the catalyst with good catalytic activity was T (o-NO 2) PPFeCl. The total yield and total selectivity of glutaric acid, cyclopentanol and cyclopentanone were 6.2% and 86.1% respectively.
