新型阴离子孪连表面活性剂的合成 总被引:1,自引:0,他引:1
系列长链环氧烷与不同短链二醇在75~80℃、NaH作用下合成了系列中间体孪连长链二醇,此中间体再与1,3-丙烷磺酸内酯在THF、NaH中反应得到了疏水链长度和连接基长度不同的7种磺酸盐孪连表面活性剂。核磁共振氢谱及红外光谱的结构分析证实了它们的结构。它们的表面张力为26.5~34 mN/m,临界胶束浓度为0.001~0.01 mmol/L,结果表明,它们的表面活性比相应碳链的常规表面活性剂强很多。疏水链长度和连接基长度的增长,有助于表面活性的提高。 相似文献

Sulfonated Gemini surfactants are a relatively new class of anion surfactants, composed of 2 or more sulfonated surfactant monomers connected by a spacer at or near the head groups through a covalent bond. In general, the sulfonated Gemini surfactants show better properties compared to conventional anionic surfactants including better surface activity, a lower critical micelle concentration, enhanced detergency, excellent compatibility with other surfactants, and better solubility in high ionic strength systems. This article reviews the synthesis of the sulfonated Gemini surfactants using different raw materials. Based on the existing information in the literature, new ideas are proposed for the synthesis and application of the sulfonated Gemini surfactants. 相似文献

Gemini surfactants were synthesized by reaction of long-chain N-alkyl glucamines with epoxy resins. Analogous to the synthesis of gemini surfactns from long-chain N-alkyl glucamines and α, ω-diepoxides (1), the reaction in methanol at 70°C could be used to convert the starting materials
selectively and almost quantitatively. N-Octyl glucamine, N-decyl glucamine, and N-dodecyl glucamine were combined with several epoxy resins, mainly technical glycidyl ethers of diols. Syntheses involving
equimolar amounts of amine resulted in quantitative conversion of the epoxy resins, and epoxide and products could be isolated
quantitatively by removing the solvent. Gemini surfactants having hydrophobic or hydrophilic spacers were preparared according
to their structures and the hydrophilic properties of the epoxy resin. Surface tensions were measured, and foaming propertiers
were examined to characterize surface-active properties of these surfactants. The more hydrophilic products were of particularly
high surface activity. Tensiometric studies showed a reduction of surface tension to 30–34 mN/m and critical micelle concentrations
in the range of 2–35 mg/L. Comparison of gemini surfactants from long-chain N-alkyl glucamines and diepoxides of α,ω-diolefins (chain lengths: C8, C9, C10, and C14) with those based on epoxy resins showed similar or lower surface activities using hydrophobic epoxy resins and much better
surface-active properties using hydrophilic epoxy resins (e.g., based on glycerol). This, together with the easier availability,
makes the epoxy resin-based products interesting surfactants. Products having very good surface-active properties are available,
especially using glycidyl ether of aliphatic diols or glycerol. 相似文献
