烷基苯磺酸盐表面活性剂结构分析及性能评价

Structure analysis and property evaluation of alkyl benzene sulfonate (ABS) surfactant

通过研究分析国内外几种烷基苯磺酸盐表面活性剂的结构特征, 给出单、双磺酸盐的含量、纯度、相对分子质量分布及结构组成。并对这几种表面活性剂进行界面活性、粘度、热稳定性及吸附等性能评价, 筛选出适合弱碱三元复合体系的国产烷基苯磺酸盐表面活性剂。

Through study and analysis of structural characteristics of several alkyl benzene sulfonate surfactants at home and abroad, the content,purity,molecular weight distribution and structural composition of single and double sulfonates have been presented. Furthermore the properties of some surfactants have been evaluated,such as interfacial activity,viscosity,thermal stability,absorbability and so on. Finally the Chinese-made alkyl benzene sulfonate surfactants that are suitable for ASP system (Na_2CO_3) have been screened out.
