Catalytic Test. The direct hydroxylation of benzene was performed in the liquid phase in a 50 mL round-bottomed flask equipped with a reflux condenser and a magnetic stirrer. In a typical procedure, 20 mmol benzene was mixed with 0.1 g catalyst (FeP?MNTs or conventional mesoporous FePO4, synthesized as in ref 5, possessing the specific surface area of 258 m2/g, and denoted FeP?MPs) in 20 mL acetonitrile. After the mixture was heated to 333 K under vigorously stirring, 35 mmol H2O2 (30 wt %) were added within 30 min. Then, the mixture continued to react for 70 min. After the reaction, the mixture was separated by centrifugation and analyzed by gas chromatography. Quantitative calculation was achieved using o-cresol added after reaction as an internal standard. 发自小木虫Android客户端 |
