An integrated process is provided for efficiently preparing 2, 4, 5-triaminothiophenol, starting; high purity salts thereof; and complexes of 2, 4, 5-triaminothiophenol with aromatic diacids, which are precursors for making 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.
