| Abstract: | The phenol was prepared from benzene by one-step oxidation with acetonitrile as cosolvent,aqueous H2O2 as oxidant and activated carbon supported iron as catalyst,and the effect of process condition on the oxidation was investigated.The results showed that under the optimal conditions of benzene 1mL,supported iron catalyst 0.5g,acetonitrile 15mL,aqueous H2O2（mass fraction 30%） 7mL,reaction temperature 30℃ and reaction time 8h,the conversion of benzene was 22.2%,the yield and selectivity of phenol were 20.2% and 90.1% respectively. |
