| 摘 要： | 用高效液相色谱法对精对苯二甲酸(PTA)生产过程中产生的残渣中的6种有机物如对甲基苯甲醛、苯甲酸、对甲基苯甲酸、邻苯二甲酸、间苯二甲酸、对苯二甲酸的含量进行测定。6种有机物测定结果的相对标准偏差为1.42%～5.45%(n=10),加标回收率为96.0%～103.5%。该方法可以应用于产品质量控制分析。

| Abstract: | Six main organic substance in PTA process residues were determined with high performance liquid chromatography. These organic substance included 4-CBA, BA, P-TA, PA, IA, and TA. The relative standard deviation of six main organic substance determination results were 1.42%-5.45% (n=10) and recoveries were 96.0%-103.5%. The method was highly recommended for production control analysis. |
