Abstract:

Catalytic oxidation of cyclohexanol to cyclohexanone catalyzed by quaternary ammonium decatungstate, with 30%H2O2 as the oxidant, had been investigated. The effect of reaction time, reaction temperature, the oxidant amount and catalyst amount on catalytic performance were studied. The results show that the optimum reaction conditions are as follows: 50 mmol cyclohexanol, 0.06 mmol catalyst, 125 mmol H2O2, 80 ℃ reacting for 8 h; At the optimum reaction conditions, the conversion of cyclohexanol is 86.5% and the selectivity of cyclohexanone could reach 98.3%. After reaction, the catalyst is immiscible in the reaction system and could be recycled after simple filtering, and no obvious changes on the catalytic activity could be found after recycling three times.
