摘要

We report an effective method for the direct amination of benzene to aniline where aqueous ammonia was employed as aminating agent with hydrogen peroxide as oxidant and copper doped hierarchical TS-1 as catalyst, using a reactive distillation reactor under mild conditions. A desirable aniline yield (12.4%) with excellent selectivity (84.7%) was obtained under optimized conditions. A probable catalytic pathway of benzene ammoxidation to aniline over hierarchical TS-1 or metal doped hierarchical TS-1 was proposed.
