“…CAT is an important intermediate of pesticides and composed spicery. There are some traditional industrial processes for the synthesis of dihydroxybenzenes, such as aniline oxidation 3 and diisopropyl benzene oxidation. 4 Aniline hydroxylation is losing its market due to its low yield and damage to the environment.…”

We reported a highly active CuFe2O4 catalyst modified with reduced graphene oxide (CuFe2O4–RGO) by a solvothermal method. The composite catalyst was fully characterized by FTIR, XRD, Raman, TEM, and XPS, which demonstrated that the CuFe2O4 nanoparticles (NPs) with a diameter of approximately 17.8 nm were densely and compactly deposited on the reduced graphene oxide (RGO) sheets. The as-prepared CuFe2O4–RGO composites were used to catalyze phenol hydroxylation for the first time, which exhibited great catalytic activity. The conversion rate of phenol to dihydroxybenzenes reached 35.5% with a selectivity of 95.2% obtained, which is much higher than for reported systems (25.0%). The catalytic activity remained high after six cycles. More importantly, the catalyst can be easily recovered due to its magnetic separability and the organic solvent-free nature of the phenol hydroxylation process. A possible mechanism in phenol hydroxylation by H2O2 over CuFe2O4–RGO20 catalyst was also proposed.

“…The history of the presently used method for the manufacture of hydroquinone in the United States has recently been reviewed with an appraisal of uses and future prospects (163). The method described consists of the oxidation of aniline to quinone by means of an excess of manganese dioxide and sulfuric acid, steam distillation to separate quinone, and immediate hydrogena-.…”
