In this study, 2-(Nitroimino)imidazoline was prepared by the reaction of nitroguanidine with ethylenediamine in the presence of water at 65℃. The product was identified by using various analytical tools such as melting point, elemental analyzer, IR spectrophotometer, mass spectrometer and TLC. This compound can be used as intermediate for prepareing pesticide-imidacloprid packing and cosmetics preservative.
