间羟基-N,N-二乙基苯胺的分析方法研究

A Study on Analysis Method of m-HydroxyN,N-diethylaniline

采用气相色谱对间羟基-N,N-二乙基苯胺及其有机杂质进行分离,用峰面积归一化法进行定量分析。通过气相色谱-质谱联用仪对间羟基-N,N-二乙基苯胺及其有机杂质进行分离并定性,给出了各化合物的结构式。使用精密度数据对分析方法进行了评价。

m-Hydroxy-N,N-diethylaniline and its organic impurities were separated by gas chromatography,and their contents were quantified by peak area normalization method.m-Hydroxy-N,N-diethylaniline and its organic impurities were separated and qualitatively analyzed by GC-MS.The structural formulae of m-hydroxy-N,N-diethylaniline and impurities were presented.The analysis method was evaluated by the data of precision.
