摘要
采用气相色谱法测定环氧丙烷中乙醛、丙醛的质量分数,测定结果的相对标准偏差均小于10%,方法的回收率范围为(100±5)%,检测限低至1×10-6,证明该方法能快速、简便、准确地测定环氧丙烷中乙醛、丙醛的含量。
The mass fraction of acetaldehyde and propylaldehyde in epoxy propane was determined by gas chromatography. The relative standard deviation was less than 10%, the recovery was in the range of （ 100 ±5） per cent, and the detection limit was as low as 1 ×10-6. This method was proved to be able to rapidly, simply and accurately determine the content of acetaldehyde and propylaldehyde in epoxy propane.
