摘要
聚氧乙烯醚磺酸盐类表面活性剂是在磺酸盐型表面活性剂的疏水基与亲水基之间嵌入含有聚氧乙烯链段的新型表面活性剂。根据国内外相关文献报道,对聚氧乙烯醚磺酸盐类表面活性剂的合成工艺与性能研究进行了综述,并探讨了这类表面活性剂在原油开采中的应用前景。指出该类表面活性剂进一步研究的重点:开发和设计聚氧乙烯醚磺酸盐类表面活性剂的绿色合成工艺路线,以便工业化生产;加强疏水基团类型和EO链节数目对该类表面活性剂性能的影响研究,寻求综合性能较合适的疏水基团和EO链节数目组合;研究聚氧乙烯醚磺酸盐类表面活性剂与其他表面活性剂的复配,拓展其在三次采油及其他领域中的应用。
Polyoxyethylene ether sulfonate surfactants are a novel type of surfactants, of which a polyoxyethylene chain is embedded between hydrophilic ionic and hydrophobic group tail to meet the needs of tertiary oil recovery. According to the domestic and foreign related literatures, the surface activity properties, foam properties, emulsifying properties, antiscaling performance, thermal stability and salt resistance, and the application prospect of this kind of surfactants in the exploitation of crude oil were discussed. It was pointed that further development of the polyoxyethylene ether sulfonate surfactants should focus on the following aspects which were designing and developing the green synthesis routes of polyoxyethylene ether sulfonate surfactan4 strengthening the performance of the hydrophobic groups type and the EO number of the surfactants, seeking for better comprehensive performance surfactants, synergizing the polyoxyethylene ether sulfonate surfactants with other surfactants to expand the application in tertiary oil recovery and other fields.
