以N-羟基邻苯二甲酰亚胺(NHPI)和磺化酞菁钴(CoSPc)组成的催化体系对环己烷的氧化反应进行了研究,通过对反应时间、温度、NHPI用量、磺化酞菁钴用量的考察,得出环己烷氧化的最优反应条件为:反应时间2h,反应温度80℃,n(环己烷)∶n(NHPI)=10∶1,n(NHPI)∶n(CoSPc)=6∶1。在气相色谱上用内标法进行氧化反应产物的组成分析,产物除了环己酮和环己醇外,还发现了乙酸环己酯。在最优反应条件下,环己酮、环己醇、乙酸环己酯的产率及总产率为10.5%、1.1%、0.4%和12.0%。
The oxidation reaction of cyclohexane with N-hydroxyphthalimide (NHPI) and sulfonated cobalt phthalocyanine (CoSPc) was studied. The effects of reaction time, temperature, amount of NHPI, The optimum reaction conditions of cyclohexane oxidation were as follows: reaction time 2 h, reaction temperature 80 ℃, n (cyclohexane): n (NHPI) = 10:1, n n (CoSPc) = 6: 1. The composition of the oxidation reaction product was analyzed by gas chromatography with internal standard method. The product was found to contain cyclohexyl acetate in addition to cyclohexanone and cyclohexanol. The yields and overall yields of cyclohexanone, cyclohexanol and cyclohexyl acetate were 10.5%, 1.1%, 0.4% and 12.0% under the optimal reaction conditions.
