考察了实验室自制的酰亚胺基取代双核酞菁铁(FeBPcN)催化氧化环己烷的性能,所用氧化剂为叔丁基过氧化氢,探讨了反应时间、反应温度、催化剂用量、溶剂、氧化剂用量及加入方式对该催化反应的影响。得出实验室自制的双核酞菁铁催化氧化环己烷的最优化条件为:反应压力:常压;反应温度:25℃;反应时间:20h;环己烷用量:2mL;催化剂用量:0.02g;氧化剂用量:10mLt-BHP;氧化剂加入方式:1.25mL/h滴加。自制酰亚胺基取代双核酞菁铁与卟啉铁、酞菁铁相比,催化性能无明显差别且容易回收,回收一次和回收两次后酮醇产率分别为17.0和17.1,仍能保持原有的催化氧化性能。
The properties of cycloheximide catalyzed by FeBPcN were investigated. The oxidant used was t-butyl hydroperoxide. The effects of reaction time, reaction temperature, catalyst amount, solvent, oxidant The effect of dosage and adding method on the catalytic reaction. The optimum conditions for cyclohexane oxidation catalyzed by binuclear phthalocyanine iron in laboratory were obtained as follows: reaction pressure: atmospheric pressure; reaction temperature: 25 ℃; reaction time: 20h; amount of cyclohexane: 2mL; amount of catalyst: 0.02g ; Oxidant dosage: 10mLt-BHP; oxidant adding mode: 1.25mL / h dropping. Compared with iron porphyrin and iron phthalocyanine, the imide-substituted binuclear phthalocyanine iron has no obvious difference in the catalytic performance and is easy to be recovered. The ketoalcohol yields of the imide-substituted binuclear phthalocyanine irons after being recovered once and twice are 17.0 and 17.1, respectively, The original catalytic oxidation performance.
