摘要：

V-MCM-41 catalysts were prepared using five concentrations of VOSO4. The resulting catalysts were characterized by FT-IR, XRD and nitrogen adsorption-desorption measurements. They were used for the direct amination of benzene to aniline. Experimental results showed that the catalytic activities of these catalysts were related to the vanadium content. The highest conversion of benzene was 68.7% over V-MCM-41(60), with a benzene-to-hydroxylamine ratio of 1:1, benzene 11.25 mmol, NH2OH 11.25 mmol, temperature 70 degrees C, catalyst amounts 0.05 g, acetic acid 7.5 mL (70 vol.%), and reaction time 2 h.
