The synthesis of 1,3-diamino-1,2,3-trioximinopropane from the reaction of malononitrileoxime with hydroxylamine is the key step for the preparation of furazan derivatives. The kinetics of this reaction was studied by ultraviolet absorption spectrometry. The results showed that the overall reaction was of the second-order and the order of reaction for malononitrileoxime and hydroxylamine was first-order for each. The reaction rate constant at 10 ℃ was 0.0679 L•mol-1•min-1. It was demonstrated that the velocity of the reaction would speed up with the increase of the malononitrileoxime concentration, the hydroxylamine concentration, and the temperature.

Key words: furazan derivatives, malononitrileoxime, 1,3-diamino-1,2,3-trioximinopropane, hydroxylamine, reaction kinetics
