摘　　要：将国内某油田减二线、减三线石油磺酸盐提纯后,通过电喷雾质谱、核磁氢谱、燃烧色谱等方法对其进行结构分析。结果表明,减三线石油磺酸盐的分子量分布较减二线石油磺酸盐宽,且减三线石油磺酸盐的数均分子量、烷链支化度、芳香度及磺化度均高于减二线石油磺酸盐。The purified second and third vacuum side petroleum sulfonates were analyzed with ESI-MS mass spectrum,1H-NMR and elemental analysis,and compared.The results show that the third vacuum side petroleum sulfonates have wider molecular weight distribution,higher average molecular weight,higher branching degree,higher aromaticity and higher sulfonation degree than the second vacuum side petroleum sulfonates.

关 键 词：石油磺酸盐 分子量分布 烃基结构
