【Abstract】 In this paper a methol of separating analysis of diphenylamine stabilizer in single-base propellant 9/7 by the reversed-phase high performance liquid chromatography is described, The chromatographic conditions were: the stationary phase: Zorbax ODS column; the mobile phase: CH₃OH/H₂O（90/10 V/V）; the detector: photodiode array detector. The detected three dimensional spectro-chromatograms of the diphenylamine stabilizer and the decomposed product were observed and analysed qualitatively. The quantitative analysis has performed by the external standard for the SPD-2AS UV detector and the CR—2Axmicroprocessor. The results were as follows: the standard deviation, 7.5×10^-3 relation, -0.47％; variable coefficient, 0.52; recovery 99.6％. It could be observed from the results of quantitative analysis and the three dimensional spectro-chromatograms that diphenylamine has decreased gradually and the decomposing product has increased as the time of store has prolonged. The time of analy-sis may be shortened to several minutes and the disturbance of determination by the decomposing product from volumetric bromide method has been overcome.更多还原
