摘要： A process is provided for the preparation of 1-amino-3-halo-4,6-dinitrobenzene and related compounds by monoamination of dihalodinitrobenzenes by ammonia in the presence of solvent and water. Using glycol as a solvent for the dihalodinitrobenzene and feeding ammonia at a rate at which it is consumed allows for the synthesis of high purity product, such as 1-amino-3-chloro-4,6-dinitrobenzene, at high yields.
摘要翻译： 提供了一种通过在溶剂和水存在下用氨将二卤代硝基苯单胺化制备1-氨基-3-卤代-4,6-二硝基苯及相关化合物的方法。 使用乙二醇作为二卤代硝基苯的溶剂并以其消耗的速率供给氨，可高产率地合成高纯度产物如1-氨基-3-氯-4,6-二硝基苯。

摘要： An integrated process is provided for efficiently preparing 2,4,5-triaminophenol, starting with nitration of 2,6-dihalobenzene; high purity salts thereof; and complexes of 2,4,5-triaminophenol aromatic diacids, which are precursors for making polybenzimidazole polymer for high performance fibers. The process design eliminates several costly intermediate drying and recrystallization steps. The handling of solid materials with possible skin sensitizing properties and toxicity is avoided, thereby eliminating human and environmental exposure.
