摘要: Abstract 5-Amino-2-formylbenzene sulfonic acid (ABAS) as a by-product during reduction of 4,4′-dinitrostilbene-2,2′-disulfonic (DNS) by Zero-Valent Iron has been detected. Experiments show that the pH and temperature are most important factors controlling formation ABAS. In addition, diluted solution DNS ( C double bond Fe(OH) 2+ between DSD may occur process. we provide mechanistic explanations for pH, initial concentration dependences ABAS formation. Optimized conditions with being 5.5 rapid cooling following incubation have applied to yield purity more than 99.0%.
