Nitrogen → Cyclohexanone

Participants

Reaction Steps

In a 316 stainless steel reactor having an internal volume of 300 ml, 26 g (309 mmol) of cyclohexane, 14 g of acetic acid, and 100.8 mg (0.617 mmol) of N-hydroxyphthalimide were placed, and the reactor was sealed and was pressurized to 50 Kg/cm2 (4.9 MPa) with a gaseous mixture comprising 50% of O2 and 50% of N2. The liquid temperature was raised on an oil bath and was held at 110° C. Immediately after the liquid temperature reached 110° C., absorption of the gas began. The reaction was terminated by cooling 60 minutes later. A reaction mixture was diluted with 60 g of acetic acid to thereby dissolve all of solid matters. The resulting solution was analyzed to find that a conversion from cyclohexane was 0.23% and adipic acid was not produced. In addition, cyclohexanone (selectivity: 53.4%), cyclohexanol (selectivity: 46.1%), and cyclohexyl acetate (selectivity: 0.5%) were produced.
