ABSTRACT:
Described is a cyclic process for preparing p-phenylenediamine from aniline and ammonia including aminating iodoaniline, recovering the iodide from the amination, and electrolyzing the iodide with aniline back to iodoaniline. Also described are the two basic reactions of the cyclic process, a new process for preparing phenylenediamines by the amination of the corresponding iodoanilines with ammonia in the presence of copper metal or a copper(I) salt and a new process for preparing p-iodoaniline by electrolysis of aniline with ammonium iodide as well as a new compound useful in the amination.
