1,3,5-triaminobenzene preparation process and its hydrolization in high purity floroglucinol

摘要

"Process of preparation of 1,3,5-triaminobenzene, floroglucinol, use of a floroglucinol and use of 1,3,5-trichlorobenzene". The present invention is a process for the preparation of 1,3,5-triaminobenzene, characterized in that it comprises an amination step of a compound of formula (1) in which: a represents a halogen atom or a group nh ~ 2 ~, x ~ 1 ~ ex ~ 2 ~, which are identical or different, each represents a halogen atom, said amination step being carried out in the presence of ammonia and a catalyst chosen from the group consisting of salts of copper, cupric and cuprous oxides or mixtures thereof at a temperature ranging from 150 198 to 250 198 and a pressure greater than 35 bars.
