    摘要: A process is provided for the preparation of 1,3-diamino-4,6-dinitrobenzene by amination of 1,3-dihalo-4,6-dinitrobenzene. The presence of water advantageously results in a highly pure product, free or essentially free of glycol ether impurities.

    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: 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.

    摘要: One or more triorganophosphite components are separated from a crude phosphite mixture containing acidic hydrolysis products. The crude phosphite mixture is contacted with a basic additive to produce a second mixture comprising a first phase and a second phase. The first phase comprises the basic additive and one or more acidic hydrolysis products and the second phase comprises one or more triorganophosphite components.
