摘　　要：混合硝化法制备硝化甘油/1,2,4–丁三醇三硝酸酯混合酯(NG/BTTN)已经实现工业化生产,为满足工业生产的需要,建立了利用高效液相色谱仪测定NG/BTTN混合酯中NG和BTTN含量的方法。该方法简单快速,标准偏差≤0.46%,相对误差≤0.49%,具有重复性好、准确度高的优点。能够满足生产的需要,实现对混合酯中NG和BTTN含量的准确测定。同时对外标法和色谱峰面积归一化法进行了对比。The preparation of nitroglycerin/l, 2, 4-butanetriol trinitrate （NG/BTTN） mixed ester lay co-nltratxon method has been industrialized. In order to meet the demand of industria! production, the method for determining NG and BTTN contents in the NG/BTTN mixed ester by using high perfor^aance liquid chromatography （HPLC） was established. This method is simple and rapid, the standard deviation is not more than 0.46%, the relative error is not more than 0.49%, and this method has the advantages such as good repeatability and high accuracy which can meet the needs of production and can realize accurate determination of NG and BTTN contents in the mixed ester. Meanwhile, the external standard method and chromatographic peak area normalization method were compared.
