脂肪叔胺是精细化工的主要原料,用它可生产出多种阳离子型表面活性剂。目前,脂肪叔胺的分析,国内主要是采用化学定氮法,国外曾报道过用色谱分析的结果。我们采用甲基乙烯基硅橡胶交联毛细管柱,对C_(11)—C_(13)(C_(11)叔胺系指N,N-二甲基十一胺,下同)、C_(16)—C_(19)二种系列脂肪叔胺,进行了色谱分离,采用色谱方法和色谱—质谱方法 Fat tertiary amine is the main raw material of fine chemicals, use it to produce a variety of cationic surfactants. At present, the analysis of fatty tertiary amine mainly adopts the chemical nitrogen fixation method in China, and the result of chromatographic analysis has been reported abroad. We used methyl vinyl silicone rubber cross-linked capillary column, C_ (11) -C_ (13) (C_ (11) tertiary amine refers to N, N- dimethyl undecylamine, the same below), C_ ) -C_ (19) two series of fatty tertiary amines, were chromatographed, using chromatographic methods and chromatography - mass spectrometry
