Phenol und anilin
WebBromination of both phenol and aniline is difficult to control, with di- and tri-bromo products forming readily. Because of their high nucleophilic reactivity, aniline and phenol undergo substitution reactions with iodine, a halogen that is normally unreactive with benzene derivatives. The mixed halogen iodine chloride (ICl) provides a more ... WebJan 1, 1997 · Catalytic amination of phenol into aniline is promising to reduce the cost for the conventional raw material. One possible way for this reaction is the formation of aniline ffa hydrogenated intermediates over a noble metal catalyst under the presence of high pressure hydrogen [1]. Another is the direct amination of phenol over a solid-acid ...
