One-Step Hydroxylation of Benzene to Phenol Induced by Glow Discharge Plasma in an Aqueous Solution

摘要

Direct phenol synthesis from benzene in aqueous solution where water was used as the oxidant through glow discharge plasma (GDP) process was described for the first time. The effect of pH, ferrous and cupric ions on the phenol yield and selectivity was examined. Phenol yield of 8.3% and selectivity of 81% has been achieved.
