Hydroxylation of Benzene in the System Vanadium(V)-Hydrogen Peroxide-Acetic Acid

摘要

Hydroxylation of benzene in acetic acid at 323 K was studied in the presence of a sodium orthovanadate catalyst.With hydrogen peroxide as aqueous solution,the yield of phenol was 12-14%.With hydrogen peroxide generated from dry sodium peroxide,the yield of phenol could be improved to 21-23%.The apparent decomposition rate constants of hydrogen peroxide in acetic acid are presented.
