Reaction Steps

EDTA (8 g) and cyclohexylamine (100 g) was dissolved in methanol (96 ml) to give a stock solution. In a separate container picric acid (1.0 g, including approximately 0.15 g of water present in the picric acid as purchased) was dissolved in methanol (100 ml) to form a picric acid/methanol solution. FeSO4.7H2O (0.03 g) was then added to the picric acid/methanol solution and was dissolved with stirring to obtain a green iron (II) picrate solution. Finally, approximately 0.96 ml of the EDTA/cyclohexylamine/methanol stock solution was added with agitation to the green iron (II) picrate solution until the green color disappeared and a clear yellow solution was obtained.
