摘　　要：用乙醇对草酰氯进行柱前衍生化,通过气相色谱法测定草酰氯的含量。以苯甲酸乙酯为内标物,OV-225毛细管柱分离,氢火焰离子化检测器检测。在选定的色谱条件下,衍生物、内标物及杂质能得到有效分离,并能获得较好的检测效果。分析结果表明,草酰氯的线性相关系数为0.999 8,回收率为99.1%~100.9%,变异系数为0.52%。Oxalyl chloride was preliminarily derivatized with ethyl alcohol,quantitative analysis of oxalyl chloride by GC with OV-225 capillary column.Ethyl benzoate as internal standard and FID detector was described.The result showed that the linear correlation coefficient was 0.999 8,The average recoveries of prodiamine added were 99.1%~100.9%,RSD was 0.52%.
