摘　　要：为了分析评价新疆油田石油磺酸盐样品中具有较优界面活性和乳化性能组分的结构特征,采用液相色谱分离方法,通过内径21 mm、长250 mm的疏水型反相色谱柱对石油磺酸盐进行精细组分切割,并对各组分的结构、界面活性和乳化性能进行表征。结果表明,用液相色谱分离方法可将石油磺酸盐样品进行有效切割,获得14种结构与组成差异较大的组分。从中筛选出1种具有最优界面活性和乳化性能的组分;该最优组分的平均相对分子质量为432.5(不含Na+),相对分子质量分布范围为390数470,并集中在405数445之间。最优活性组分在石油磺酸盐样品中的含量为20.34%。通过严格筛选和控制反应原料油和生产工艺,可提升石油磺酸盐样品的性能。In order to analyze and evaluate the characteristics of the component with good interfacial activity and emulsifying property in petroleum sulfonate of Xinjiang oilfield,the liquid chromatography was adopted to perform the fine components separation. The preparative column was a hydrophobic reversed phase column with diameter of 21 mm and length of 250 mm.Structural composition,interfacial activity and emulsifying property were also completed. The results showed that the petroleum sulfonate sample could be effectively separated into fourteen components with obvious structural differences,among which one component with the most excellent interfacial activity and emulsifying property was distinguished. The average molecular weight and distribution range of this component was 432.5(without Na^+)and 390-470,respectively. And molecular weight distributing between 405 and 445 was prominent. The mass percentage of most excellent component in petroleum sulfonate was 20.34%. The performance of petroleum sulfonate sample could be improved through the rigorous screening and control for feedstock and production process.
