阳-非离子型双子有机硅表面活性剂的制备及性能研究

摘要

A kind of novel cationic and nonionic type Gemini organic silicon surfactant (QAGS) was synthe⁃sized through hydrosilylation and quaternization ring- opening reaction using the terminated hydrogen polydimeth⁃ylsiloxane (PHMS), al yl polyoxyethylene polyoxypropylene epoxy groups ether (APEE) and triethylamine (TEA) as the raw materials. The chemical structure of QAGS was characterized by IR. The properties of QAGS, such as critical micel e concentration (cmc), critical surface tension (γcmc), and stability in hard water were tested. The results showed that the cmc of QAGS solution was 1.0 g/L, γcmc of QAGS solution was 25.7 mN/m, and the sta⁃bility of QAGS in hard water was grade 5.%以端含氢硅油（PHMS）、烯丙基聚氧乙烯聚氧丙烯环氧基醚（APEE）和三乙胺（TEA）为原料，经硅氢加成反应和季铵化开环反应合成了一种阳-非离子型双子有机硅表面活性剂（QAGS）。用红外光谱对QAGS的结构进行了表征，并对QAGS的临界胶束浓度（cmc）、表面张力（γcmc）以及耐硬水稳定性等进行了测试。结果表明，QAGS的cmc为1.0 g/L，γcmc为25.7 mN/m，在硬水中的稳定性达5级。
