NH4F modified β zeolite for aniline condensation to diphenylamine and its catalytic mechanism

Autor: Yingling Liao, Xuan Meng, Li Shi, Naiwang Liu

Publikováno v: Catalysis Communications, Vol 175, Iss , Pp 106624- (2023)

The main factors affecting the performance of solid acid catalyzed liquid-phase condensation of aniline to diphenylamine are acidity and pore structure. Fluorine has strong electron affinity due to its special electronic structure, which can adjust t
