Abstract 

Fe-D72 resin was prepared by the ion exchange process between iron ions and D72 resin. It was applied to the phenol hydroxylation with H2O2. The effects of different reaction conditions such as the iron capacity of catalyst, reaction temperature, reaction time, catalyst dosage, molar ratio of H2O2 to phenol were investigated. The orthogonal experiment was carried out to get the best optimized operating conditions. Under the conditions of iron capacity as 95.4 mg·g-1, reaction temperature as 70 ℃, reaction time as 1 h, catalyst dosage as 0.1 g, molar ratio of H2O2 to phenol as 1∶1, 42.4% phenol conversion was obtained with benzenediol selectivity being 94.1%. The reusability of prepared catalyst illustrated that it could be recovered and reused without notable loss of activity.
