| Abstract: | The components of the unsymmetrical dimethylhydrazine (UDMH) in liquid propellants were analyzed by gas chromatography-mass spectrometry . The retention behavior of the chromatography and the cleavage mechanism of the mass spetra of components were studied . And the influence of each component on specific impulse of the propellant was analyzed .The result showed that the UDMH in liquid propellant contains impurities of water , unsymhydrazone ,dimethylamine and acetaldehyde dimethylhydrazone etc.Except for dimethylamine , other impurities will reduce the specific impulse of the propellant . |
