Sažetak

The paper describes the reactions of aminopentacyanoferrate(II)-ions with four different pralidoximes: PAM-20H, PAM-2Cl, PAM-2CH3S03 and PAM-2J. It was found possible to distinguish spectrophotometrically between the examined oximes because of the different rates of their reaction with the pentacyanidic reagent and different stabilities of the produced complexes (PAM-21 from the other three oximes) as well as because of different absorbances measured in given experimental conditions (PAM-20H from the other three oximes). By paper chromatography, with the use of the solvent system n-propanol: water - 70:30 it was possible to distinguish pralidoxime chloride (PAM-2Cl) from the other three oximes because of its lowest rate of migration. The use of a water solution of sodium aminopentacyanoferrate(II) as »spray« reagent for the identification of pralidoximes is recommended. The complex product of these reactions has been isolated.
