摘要：

为探究环氧丙烷（PO）和1, 2-环氧丁烷（BO）改性对脂肪醇聚氧乙烯醚（AEO7）性能的影响，本研究系统比较了AEO7及其在PO/BO改性下的耐盐性、耐碱性能、泡沫性能、乳化稳定性、润湿性、浊点、冻点及去污性能等关键性质。结果表明，PO或BO基团的引入普遍降低了AEO7的耐碱性，且BO的负面影响更为显著，改性同时改变了其盐耐受性，BO的引入显著降低了产物的水溶性与盐容忍度，PO与BO均能加快泡沫破裂的动力学过程，其中BO改性样品表现更优。由于疏水尾链与油相相容性的改善，改性产物的乳化能力得到显著增强，润湿性能亦获得提升，尤其是BO改性样品。此外，PO/BO的引入导致浊点与冻点明显下降，其降低幅度与疏水基团的类型和接入数量相关；在去污力方面，PO改性提升了对皮脂污布的去污率，而BO的引入则降低了对炭黑污布和皮脂污布的清洁效率。该研究为烷氧基化表面活性剂的定向分子设计与性能优化提供了实验依据与理论指导。

Abstract:

This study aimed to elucidate the impact of propylene oxide（PO）and 1, 2-butylene oxide（BO）incorporation on the properties of AEO7 surfactant. A comparative investigation was conducted on the salt tolerance, alkali resistance, foaming, emulsification, wetting ability, cloud point, pour point, and detergency of the pristine and modified surfactants. The results demonstrated that the introduction of PO or BO groups generally compromised the alkali resistance of AEO7, with BO exerting a more detrimental effect. Modification also altered salt tolerance, and BO incorporation notably reduced water solubility and salt tolerance. Both PO and BO significantly accelerated defoaming kinetics, with BO-modified variants exhibiting superior performance. Emulsifyingability was markedly enhanced due to improved compatibility between the surfactant hydrophobic tail and the oil phase. Wetting performance was also improved, particularly in BO-modified samples. Furthermore, the incorporation of PO/BO led to a distinct reduction in both cloud point and pour point, which showed a clear correlation with the type and extent of hydrophobic modification. Regarding detergency, PO modification improved the removal of sebum soil, whereas BO incorporation reduced the cleaning efficiency for both carbon black and sebum soils. This work provides fundamental experimental evidence and theoretical insights for the targeted molecular design and performance optimization of alkoxylated surfactants.
