摘要

本研究以酸性离子交换树脂为催化剂，在温和（0 °C、常压）、无溶剂的条件下，开发了一种在 NO2-O2 体系中催化苯硝化为硝基苯的绿色高效方法。根据实验筛选，确定商用酸性离子交换树脂 Amberlite FPC3500 为最佳催化剂。在优化的反应条件下，苯的转化率为 99.9%，硝基苯的选择性为 99.1%。此外，催化剂还可以方便地重复使用。这些结果证明了生产硝基苯的更环保路线。

Nitration of Benzene to Nitrobenzene Using NO2 as Nitro Source Under Mild and Solvent-Free Conditions

In this work, a green and efficient method has been developed to catalyze the nitration of benzene to nitrobenzene in NO₂-O₂ system by using acidic ion exchange resin as catalyst under mild (0 °C and atmospheric pressure) and solvent-free conditions. Based on experimental screening, commercial acid ion exchange resin Amberlite FPC3500 was identified as the optimal catalyst. Under the optimized reaction conditions, 99.9 % conversion of benzene was obtained with 99.1 % selectivity of nitrobenzene. Furthermore, the catalyst is easily reusable. The results demonstrate a greener route for the production of nitrobenzene.
