毛细管色谱分析二级不皂化物前馏分中的脂肪醇和烷烃

Capillary Chromatographic Analysis of Alkanes and Fatty Alcohols in the Secondary Unsaponifiable Head Fraction

二级不皂化物是石蜡氧化生产合成脂肪酸的中间产物,其主要组分为脂肪醇和烷烃及其它含氧化合物。关于脂肪醇中烷烃的分析国外曾有报道,Lang应用分子筛分离正构烷烃和异构烷烃及正构醇。近年来,中科院大连化学物理研究所做了工业脂肪醇及其杂质的分析研究,但是。

The separation of alianes and falty alcohols in the secondary unsaponifiable head fraction was perlormed with a modilied SP-2305 Chroma-tograph under linear temperature programming-The column used was a 31m×0.25mm i.d.glass capillary column crosslinled methyl vinyl silicone gum.All alranes and fatty alcohols were resolved and identiiied under the experimental conditions.Their quantitation correction factors were mca-sared,Good reproducibility was obtained.
