Study on technology of catalyzed oxidation of cyclohexanol to cyclohexnone by decatungstate

A new type of decatungstate( [Mor1,2]4W10O32) was synthesized,puried,characterized and applied as catalyst in cyclohexanol oxidation. [Mor1,2]4W10O32was used as catalyst and 30% H2O2 as oxidant,oxidizing cyclohexanol to cyclohexanone. The effects of different amounts of catalyst,oxidant,reaction temperature and reaction time on the yield were systematically studied. The suitable reaction condition of cyclohexanol oxidation was suggested: at 80℃,cyclohexanol( 5mmol),catalyst( 30 μmol) and H2O2( 12. 5 mmol),and reacted for 8 h,the yield was 96%.
