摘要
到激活的支持碳的 Fe (Fe/AC ) 作为氧化剂用 H2O2 在 acetonitrile 催化的酚的苯的直接 hydroxylation 在一个连续流动反应堆被学习。结果证明连续操作能获得 28.1% 的高酚产量，在温和状况下面结合了 98% 的 3 h1，和高选择的周转频率。催化剂被 N2 吸附 / 解吸附作用， Boehm 滴定， X 光检查光电子系列，和 Fourier 变换描绘红外线的光谱学。铁可以与形成象种类一样的铁羧化物的 carboxyl 组一起交往，这被观察，它充当活跃阶段。适合一个 Arrhenius 模型到试验性的数据获得的明显的激活精力是 13.4 kJ/mol。反应顺序被计算是大约 1， 0.2 为苯并且 0.7 为 H2O2。
The direct hydroxylation of benzene to phenol catalyzed by activated carbon-supported Fe （Fe/AC） in acetonitrile using H2O2 as the oxidant was studied in a continuous flow reactor. Results showed that the continuous operation could obtain high phenol yield of 28.1%, coupled with the turnover frequency of 3 h^-1, and high selectivity of 98% under mild condition. The catalyst was characterized by N2 adsorption/desorption, Boehm titration, X-ray photoelectron spectra, and Fourier transform infrared spectroscopy. It was observed that iron may interact with the carboxyl group forming iron-carboxylate like species, which act as the active phase. The apparent activation energy obtained by fitting an Arrhenius model to the experimental data was 13.4 kJ/mol. The reaction order was calculated to be about i, 0.2 for benzene and 0.7 for H202.
