説明

Attempts have been made to separate p-nitrophenol, 2, 4-and 2, 6-dinitrophenol and 2, 4, 6-trinitrophenol by paper chromatography and by paper electrophoresis. In the paper chromatography, when a mixture of nitrophenols was developed with amylalcohol-benzene mixture containing citric acid buffer solution on a filter paper strip impregnated with the same buffer solution or when it was developed with amylalcohol-benzene-acetic acid on a filter paper strip impregnated with sodium acetate, good separatons were obtained. In the paper electrophoresis, migration in acetic acid-sodium acetate buffer solution at pH 3.23.6 for 1.5 hours at 500 volts gave a complete separation.<BR>With an object of separating 2, 6-dinitrophenol and 2, 4, 6-trinitrophenol in 2, 4-dinitrophenol, separation by column electrophoresis has been investigated and it was confirmed that the determination of 0.25% of 2, 6-dinitrophenol and 2, 4, 6-trinitrophenol was possible. The determination of 2, 6-dinitrophenol in a commercial 2, 4-dinitrophenol was also made.
