Abstract

Abstract:

Combined with synchronized monitoring techniques, the active constituent in the sample of alkylbenzene sulfonates was separated and purified by liquidliquid extraction method. The results showed that the active constituent with higher purity can be obtained and the content data were more accurate adopting the present optimized purification process. Meanwhile, the residual content of active constituent of alkylbenzene sulfonates in the coexist constituents, such as unsulfonated oil, inorganic salts etc. was less than 1% of the total active amount. The content of active constituent of alkylbenzene sulfonates increased from about 39% to 48% compared to the purification process that is usually used previously.

Key words: Alkylbenzene sulfonate, Active constituent;, Purification;, Content

摘要：

结合同步监控技术，采用液液萃取法对烷基苯磺酸盐样品中的烷基苯磺酸盐活性物进行分离纯化。结果表明，优化后的纯化工艺可以获得纯度较高、结果更为准确的烷基苯磺酸盐活性物组分，样品中其它共存组分如未磺化油、无机盐等中残留的烷基苯磺酸盐活性物的量小于总活性物量的1%；采用优化后的纯化工艺获得的烷基苯磺酸盐活性物质量分数较常规纯化工艺有明显增加，从39%左右增加至48%以上。
