摘要
建立了用气相色谱法同时测定电合成芳醛工艺中对溴苯甲醛和对溴甲苯的方法。选用OV - 17为固定相 ,正十四烷为内标物 ,在选定的色谱条件下分别用归一化法和内标法测定样品 ,结果 ,标准偏差≤ 0 3% ,回收率为 99 7%～ 10 1 0 % ,分析结果与常规的化学分析法吻合 ,该方法简便、快速、准确。
The optimum conditions of GC Analysis were investigated for sample of p-bromobenzaldehyde in electrosynthesis. OV - 17 was chosen as stationary phase and n-tetradecane as internal standard. The results indicated that this method was rapid and accurate. The standard deviation was lower than 0.3% and the rate of recovery was 99.7% - 101.0%.
