Embodiment 1
[0024] In a 100mL stainless steel autoclave with polytetrafluoroethylene liner, 0.0016g (0.0020mmol) 5,10,15,20- tetrakis (4-chlorophenyl) porphyrin cobalt (II) and 0.0363g (0.20 mmol) anhydrous copper acetate dispersed in 16.8320 g (200 mmol) cyclohexane, seal the reaction vessel, stir and raise the temperature to 120° C., and feed oxygen to 1.0 MPa. At 120°C, 1.0MPa oxygen pressure, 800rpm stirring reaction for 8.0h. After completion of the reaction, cool to room temperature with ice water, add 1.3115g (5.00mmol) triphenylphosphine (PPh 3 ), stirred at room temperature for 30min to reduce the generated peroxide. Using acetone as solvent, the resulting reaction mixture was adjusted to 100 mL. Pipette 10mL of the resulting solution, and use toluene as an internal standard for gas chromatographic analysis; pipette 10mL of the resulting solution, and use benzoic acid as an internal standard for liquid chromatographic analysis. Cyclohexane conversion 5.96%, cyclohexanol select...
