摘要
研究和建立了一种3，4-二氟苯硼酸、3，4，5-三氟苯硼酸和对氟苯硼酸及其脱氟杂质新戊二醇酯化后产物的GC分析方法。该分析方法重现性好，分析结果相对标准偏差为3．3％-22％，脱氟杂质的添加回收率为98％-104％。
An accurate and reliable GC analysis method was studied on the neopentyl glycol-esterified products of 3,4-difluorophe- nylboric acid ,3,4,5-trifluorophenylborie acid ,4-fluorophenylboric acid and their defluorinated impurities. Excellent performances were obtained using this analysis method such as remarkable reproducibility （3.3% to 22% ） ,relative standard deviation （RSD, n = 5 ） and reproducibility （ - 10% RSD）. The recoveries of defluorinated impurities were range from 98% to 104%.
