氟胺氰菊酯是一种用于蜜蜂的高效杀螨剂。从 2 0 %商品氟胺氰菊酯粉剂中通过硅胶柱层析分离得到了 96 .6 %的纯品并用FTIR和GC MS进行定性定量测定。采用GC MS定量分析的方法 ,氟胺氰菊酯的浓度在 0 .0 5～ 10mg L范围为线性响应 ,最低检测极限为 0 .0 1mg L。采用R(- )N 3 ,5 二硝基苯甲酰 苯基甘氨酸和长链烃的硅胶微粒手性柱 ,可成功地分离氟胺氰菊酯的二种旋光异构体 ,它们在商品氟胺氰菊酯中的比例近似为 1∶1
Fluvalinate is a highly effective acaricide for bees. 96.6% of pure product was isolated by silica gel column chromatography from 20% commercial fluvalinate powder and qualitatively and quantitatively determined by FTIR and GC MS. Using quantitative analysis method of GC MS, the concentration of fluvalinate in the range of 0.05 ~ 10mg L linear response, the minimum detection limit of 0.01mg L. Two optical isomers of fluvalinate can be successfully separated using a silica gel particle chiral column with R (-) N 3, 5 dinitrobenzoylphenylglycine and long-chain hydrocarbons, The ratio of the cypermethrin is approximately 1: 1
