Research on the direct amination of benzene to aniline by NiAlPO4–5 catalyst

Abstract
A series of NiAlPO4–5 molecular sieves have been hydrothermally synthesized and shown high and stable activity in the direct amination of benzene to aniline with hydroxylamine hydrochloride as aminating agent. The as‐synthesized and calcined samples were investigated with XRD, SEM, TG, BET, NH3‐TPD and FT‐IR to explore the crystalline, coordination and location of the incorporated transition metal ions. The results indicated that nickel ions were incorporated into the framework of AlPO4–5 and the as‐synthesized catalysts were highly crystalline, and possessed good thermal stability. Among them, Ni(0.3)AlPO4–5 showed the highest catalytic activity for the direct amination of benzene with the highest aniline yield of 73.2% and 100.0% selectivity to aniline. After the catalyst was reused for 5 times, the activity remained little change.
