摘要
提出了用HP - 5毛细管色谱柱测定在萃取液中吗啉、N 甲酰吗啉及其杂质含量的分析方法 ,研究了其测定条件 ,并对分离后的组分用质谱方法进行了定性 ,按照确定的分析条件 ,对甲乙酮原料萃取剂中各组分都得到较好的分离 ,精密度好 。
In this paper, advpling HP-5 capillary gas chromatography column for determination of morpholine, N-formyl morpholine and impurities in the extraction solvent is presented. the detection conditions were studied. and the separated components were identified by mass spectroscopy. Under the determined analytical conditions,the components in the extraction solvent of butanone stock were separated with good resolution. The method is of high precision and . The analysis result is acurate and reliable.
