3,5-二叔丁基甲苯的气相色谱法分析

Determination of 3,5 Di t Butyltoluene by Gas Chromatography

用气相色谱法定量测定了反应混合物中的３，５－二叔丁基甲苯。方法简便、快速，完成一次分析仅需１０ｍｉｎ，校正曲线在１．１～９．２μｇ间呈现良好的线性关系（ｒ＝０．９９９０，ｎ＝８）。

A quantitative analytical method for 3,5 di t butyltoluene in reaction mixture by gas chromatography with methyl benzoate as internal standard is reported. A stainless steel column of 2m×3mm i. d. packed with 15% FFAP/Chromosorb W/AW (60 80 mesh) and flame ionization detector were used with column temperature of 180℃ and injection port and detector temperatures of 250℃ There was a good linear calibration curve in the range from 1.1 to 9.2μg(r=0.9990,n=8).It was taken 10 minutes to complete an analysis.
