PROCESS FOR THE SYNTHESIS OF 1-AMINO-3-HALO-4,6-DINITROBENZENE |
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. |
