Abstract

Abstract In this study, the properties of amide Gemini surfactants (DLP-12, DLP-14 and DLP-16) were investigated. The results showed that these surfactants have good wettability and solubility, but these properties deteriorate with increasing hydrophobic chain length. The critical micelle concentrations (CMC) measured by the Wilhelmy method and by the steady-state fluorescence spectroscopy were similar and showed the same trend: The CMC values decreased with increasing hydrophobic chain length. The solubilization capacities in toluene were (6320, 6440 and 6680) mL/mol for DLP-12, DLP-14 and DLP-16, respectively, indicating an improvement in solubilization ability. Thermal stability experiments showed that the initial decomposition temperatures of the three surfactants were (301, 320 and 331) °C, respectively, indicating good thermal stability of these surfactants.

酰胺Gemini表面活性剂的性能研究

摘要本文研究了酰胺类Gemini表面活性剂(DLP-12、DLP-14和DLP-16)的性质。结果表明，这些表面活性剂具有良好的润湿性和溶解度，但随着疏水链长的增加，这些性能会变差。Wilhelmy法测定的临界胶束浓度(CMC)与稳态荧光光谱法测定的结果相似，呈现出相同的趋势:CMC值随疏水链长的增加而降低。DLP-12、DLP-14和DLP-16对甲苯的增溶能力分别为(6320、6440和6680)mL/mol，表明其增溶能力有所提高。热稳定性实验表明，三种表面活性剂的初始分解温度分别为(301、320和331)℃，表明三种表面活性剂具有良好的热稳定性。
