低聚表面活性剂的合成及应用进展

Review of Synthesis and Interfacial-active Properties of Oligomeric Surfactants

介绍了柔性链烃、多分支、聚氧乙醚和刚性联接基低聚表面活性剂的合成方法 ,并对低聚表面活性剂在合成新物质、物质分离、乳液聚合、杀菌缓蚀及石油工业的应用进行了评述。

The development of modern surfactants has been in rapid progress over the last two decades. Dimeric and oligomeric surfactants are novel surfactants that are presently attracting considerable interest in the academic and industrial communities working on surfactants.These novel surfactants have number of properties different from those of their single-chain counterparts,with lower critical micelle concentrations(cmc),better wetting properties,lower surface tensions and lower Krafft point and unique aggregation morphologies. The synthesis of a number of chemical structures for anionic, amphoteric,oligomeric cationic surfactants was introduced. The application of Gemini surfactants was investigated in this paper.
