Abstract:

The reaction product of catalytic hydrogenation of nitrobenzene was determined by high performance liquid chromatography and UV detection. The reaction solution of catalytic hydrogenation of nitrobenzene was filtered by the microporous filter membrane(water system) which was 0.45 μm, and then the samples diluted with methanol were injected. The qualitative analysis of the experiment was used retention qualitative method comparing directly with the known standard material, the quantitative analysis was used external standard method. The linear regression equations of nitrobenzene, aniline and p-aminophenol are obtained from experiments, and the correlation coefficients are 0.998 6, 0.999 8 and 0.999 9, the detection limit is 2.0,20.0 mg/L and 21.0 mg/L, the coefficient of recoveries of them are 97.6%, 97.5% and 98.1%, the precisions expressed in relative standard deviation are 0.62, 0.77 and 0.36 respectively. This method is quick, accurate and simple and does not require sample pretreatment, experimental results are satisfactory comparatively.
