| Abstract: | 2-chloro-5-trichloromethylpyridine is an important intermediate in the development and production of pesticide.GC/MS was applied to the determination of 2chloro-5-trichloromethylpyridine(TCMP),an important interme-diate for the synthesis of the weedicide haloxy-fop-methyl.The optimum conditions found were as follows: Rts-5MS capillary was used as chromatographic column,ionizationa fountain was EI.Linear relationship between the peak area and concentration of TCMP was obtained in the range of 0.0001 to 10 mg/kg(r=0.9921).Recovery test was performed and average recovery of 99.05% was obtained.The relatively standard deviation was 0.78%.In the analysis of some substantial samples,TCMP was determined satisfactorily by this method. |
