An integrated process is provided for preparing complexes of 2,3,5,6-tetraminotoluene with an aromatic diacid starting with nitration of 2,6-dihalotoluene. The process design eliminates costly intermediate drying and recrystallization steps. Handling of solid materials with possible skin sensitizing properties and toxicity is avoided, thereby eliminating human and environmental exposure.
提供了一种集成工艺,用于制备2,3,5,6-四
氨基
甲苯与芳香族二酸的络合物,从2,6-二卤代
甲苯开始进行硝化。该工艺设计消除了昂贵的中间干燥和重结晶步骤。避免了固体材料的处理,这些材料可能具有致敏性和毒性,从而消除了人类和环境的暴露。
