摘    要:目的建立二丁基羟基甲苯含量测定方法。方法采用气相色谱法,以4-叔丁酚为内标,色谱柱为DB-624毛细管柱(30m×0.53mm×1μm),汽化室温度220℃,柱温180℃。载气:氮气,5mL·min^-1;检测室温度240℃,尾吹30mL·min^-1。进样量1μL。结果在0.041mg·mL^-1~1.01mg·mL^-1的范围内浓度(C)与峰面积相对响应值(f=A/A内)有良好的线性关系,r=0.9999;样品重复测定的RSD%为1.3%(n=6),日间精密度RSD%为1.2%(n=4);方法的检测限为1.2μg。结论气相色谱法可以控制二丁基羟基甲苯的含量。

Abstract:OBJECTIVE To determine butylated hydroxytoluene by GC. METHODS GC was applied to quantitative analysis. Chromatographic conditions were: DB-624 column (30m × 0.53mm × 1μm) ; Flame ionization detector(FID) ; Column temperature: 180℃ ; Injector temperature: 220℃ ; Detector temperature: 240℃ ; Nitrogen was used as carrier gas, the flow rate was 5 mL · min^-1 . An internal standard was 4-tert-butylphehal. RESULTS The calibration curve was linear in the range of 0.041mg· mL^-1 - 1.01mg· mL^-1 . CONCLUSION The GC method can be used as the quality control of butylated hydroxytoluene.
Keywords:Butylated hydroxytoluene  Determination  GC
