蒸馏废飞机除冰液所得馏分的气相色谱-质谱分析

Analysis of fraction separated in the process of distilling used aircraft deicing fluid by gas chromatography-mass spectrometry

采用气相色谱-质谱联用技术对蒸馏废飞机除冰液所得馏分进行分析,分离出了3个峰,鉴定出馏分中被蒸出的除冰液有效成分为乙二醇、2-辛酮和2-辛醇,利用峰面积归一化法确定各组分的相对含量为乙二醇占85.78%,2-辛酮占1.54%,2-辛醇占12.68%。

The fraction which was separated in the process of distilling used aircraft deicing fluid was ana- lyzed by gas chromatography - mass spectrometry（ GC - MS）, and three active components were identified. They were ethylene glycol, 2 - octanone and 2 - octanol. By the normalized method, the three components accounted for 85.78%, 1.54% and 12.68% respectively.
