| 摘 要： | 采用柱色谱和阴离子交换树脂法分离出辽河200~430℃馏分油中的环烷酸。通过电子轰击(EI)质谱(MS)分析得到的环烷酸。分别对其中的脂肪酸、一环及多环环烷酸进行谱图定性和峰强度数据处理,得到了有关结构与组成的分析结果。结果表明,辽河200~430℃馏分油中环烷酸的相对分子质量分布在186~496,碳数分布在C11~C34,其中双环、三环环烷酸的含量较高。 |

| Abstract: | The naphthenic acids in 200～430 ℃ distillate of Liaohe crude oil were separated by column chromatogram and anion exchange resin.The analysis results of naphthenic acids were obtained by the use of MS and EI techniques.The type and composition of the naphthenic acids can be classified into fatty acids,mono-,hexa-cyclic naphthenic acids according to their mass spectrum and peak intensity.The results indicate that the relate molecular weight distribution of the naphthenic acids in 200～430 ℃ distillate of Liaohe crude oil is 186～496,and the carbon number distribution is C_(11)～C_(34).The contents of bi-cyclic and tri-cyclic naphthenic acids are higher than others. |
