摘　　要：采用高效液相色谱分析方法对2,6-萘二甲酸及副产物进行检测。色谱柱为Zorbax eclipse XDB C8,流动相为乙腈和甲酸水溶液,采用缓慢梯度淋洗法。精密度试验结果表明:偏苯三酸、2,6-萘二甲酸、6-甲酰基-2-萘酸的RSD分别为0.072%、0.055%、0.087%,线性关系、精密度等均能满足定量分析的要求。High performance liquid chromatographic（HPLC）method was adopted to analyze 2,6-naphthalenedicarboxylic acid and by-products on Zorbaxeclipse XDBC8 Column.Mixture of CH3 CN and Methanoic acid aqueous solution was used as eluent with slow gradient elution method.Results of precision test show that RSD of trimellitic acid,2,6-NDCA and 6-formyl-2-naphthalene acid were 0.072%,0.055% and 0.087%,respectively.Linear relationship and precision can meet requirements of quantitative analysis.
