Electric Literature of 33786-89-9, These common heterocyclic compound, 33786-89-9, name is 5-Chloro-m-phenylenediamine, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
EXAMPLE 6 In an autoclave, 28.6 g. of 3,5-diaminochlorobenzene, 2 g. of cuprous chloride and 122 g. of 28% ammonia water were charged to react them at 165 to 170 C. for 8 hours to obtain 1,3,5-triaminobenzene. Ammonia was discharged and the product was recrystallized to obtain 19 g. of 1,3,5-triaminobenzene.
The synthetic route of 33786-89-9 has been constantly updated, and we look forward to future research findings.
