1-ammonia propyl-2-methyl imidazole was synthetizatied from catalytic hydrogenation of 1-cyanoacetate-2-methylimidazole (2MZCN), the parameters of synthetic process were investigated systematicly .And the appropriate synthetic conditions were obtained. The conversion of 2MZCN and 1-amino-propyl-2-methyl imidazole yield reached 99.7% and 94.2% after reaction 4 h respectively, under the conditions of reaction temperature of 100℃, pressure of 5Mpa, speed of 624rpm, and the solvent is saturated ethanol solution of ammonia (ratio with the quality of raw material is 2:1), Rainie nickel is the catalytic agent and potassium hydroxide act as catalyst promoter (accounting for the quality of raw material 18.9%). The product is analysed by Infrared spectroscopy (FTIR) and proton nuclear magnetic resonance spectroscopy (1H-NMR) and Gas Chromatography-Mass Spectrometer(GC-MS).
