新型农药中间体2,4-二氯苯基戊酮中的间二氯苯气相色谱分析

Analysis of m-Dichlorobenzene in the Novel Pesticide Intermediate 2,4-Dichlorovalerophenone by GC

研究了新型农药中间体2,4-二氯苯基戊酮中的间二氯苯气相色谱分离条件。以10%SE-30/Chromosorb W.AW.DMCS为固定相,氢离子火焰检测器检测。以苯甲酸甲酯作为内标物,采用内标定量分析法。测得2,4-二氯苯基戊酮中的间二氯苯的平均回收率为99.23%,相对标准偏差小于0.02%。

m-Dichlorobenzene in the sample of 2,4-dichloro-valerophenone was studied by GC with FID on a glass column packed with 10% SE-30/Chromosob W.AW.DMCS. Methyl benzoate niobe oil was used as internal standard. Internal standard method was chosen as quantitative analysis method. The result showed that the average recovery was 99.23% and the RSD was less than 0.02%.
