    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: 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.
