摘要
系统地建立了一套简单、快速、能同时定量分析甲苯液相催化氧化主要产物苯甲醛、苯甲醇及苯甲酸的气相色谱分析方法。采用FFAP毛细管柱和氢火焰离子化检测器(FID),以邻硝基甲苯为内标标定苯甲醛、苯甲醇,以邻苯二甲酸二甲脂为内标标定苯甲酸。结果表明,苯甲醛、苯甲醇、苯甲酸样品的平均回收率和标准偏差(RSD)分别为105.39%,101.94%,97.18%和3.19%,3.71%,1.66%。该分析方法简单、快速、精度高。
A specific GC analysis method was established for the rapid quantification of the main products of liquid-phase oxidation of toluene, namely, benzaldehyde, benzyl alcohol and benzoic acid. A GC equipped with a FFAP capillary and a FID detector was adopted. O-nitrotoluene and dimethylphthalate were used as internal standards of benzaldehyde, benzyl alcohol and benzoic acid respectively. The results indicated that the mean recovery rate for spiked samples are 105.39%, 101.94%, 97. 18%, respectively, and the standard deviations are 3. 19%, 3.71%, 1.66%, respectively.
