| Abstract: | The content of aliphatic diamine was determined by thin-layer chromatography (TLC). The optimum synthetic art was studied and the equation of working curve was established. The method is especially suitable for determination of the content of aliphatic diamine in polyamide resin in the presence of weak organic acid. The feature of the method is quick and effective. |
