- Abstract:
- This paper establishes a metal-free catalytic system comprising 2,2,6,6-etramethylpiperidine-l-ox-yl(TEMPO),NaClO and NaBr,catalytic oxidation of cyclohexanol to cyclohexanone. This paper studies theeffects of reaction time,pH,the dosage of the catalysts and solvent and so on. The optimum reaction condi-tions are as follows: cyclohexanol 0.3 g,TEMPO 0.005 g,NaBr 0.03 g,NaCIO 0.45 g,CH Cl,7 mL,pH9.1 and the reaction time 1 h.Three parallel experiments were performed under this condition,the averageconversition of cyclohexanol was 88.2%,and the average yield of cyclohexanone could reach 87.3%.
