对二甲苯电合成法制备对甲苯甲醛的气相色谱分析
GC ANALYSIS OF P- TOLUALDEHYDE PREPARED FROM P-XYLENE BY USING THE ELECTROSYNTHESIS METHOD
【摘要】 研究了对甲苯甲醛的气相色谱分析条件。分别选用 8%OV - 2 1 0 ,1 0 %QF - 1和 8%DC - 2 0 0为固定相测定对甲基苯甲醛的含量。结果表明 :本方法快速、准确 ,标准偏差小于 0 2 %,回收率为 1 0 0 5 %~1 0 1 0 %。
【Abstract】 The GC analytical method of p tolualdehyde prepared from p xylene by using the electrosynthesis has been given in this paper.8% OV-210 chromosorb or 10% QF-1+8% DC-200 were chosen as the stationary phase.The standard deviation and recovery of this method were less than 0.2% and 100.5%,respectively.The results show that this method is rapid and accurate.
