摘　　要：2,7-二甲基-2,3-二氢-苯并呋喃-6-甲酰氯,(简称苯并呋喃甲酰氯)与无水甲醇反应,生成2,7-二甲基-2,3-二氢-苯并呋喃-6-甲酸甲酯(简称苯并呋喃甲酸甲酯)后,采用气相色谱法,选用5%OV-210/ChromosorbWAW-DMCS(80-100目),Φ3.2mm×1m柱,邻苯二甲酸二乙酯为内标物,分离测定呋喃虫酰肼的重要中间体苯并呋喃甲酰氯的含量。方法的平均标准偏差为0.18,平均变异系数0.22%,平均回收率99.99%。该方法快速、准确,可以实际应用于苯并呋喃甲酰氯的生产监测和质量控制。A quantitative analysis method of 2,7-dimethyl-2,3-dihydroben -zofuran-6-earbonyl chloride, which is a key intermediate of the Fufenozide insecticide, was established based on GC analysis of its methyl ester. A Φ 3.2mm×1m glass column packed with 5% OV-210/Chromosorb W AW- DMCS （80-100） was used, and diethyl phthalate used as the internal standard material. The results showed that the average standard deviation was 0.18, the average variation coefficient was 0.22% and the average recovery was 99.99%. The method is rapid and accurate for the determination of 2,7-dimethyl-2,3-dihydrobenzofuran-6-carbonyl chloride on production line.
