季铵盐型有机硅双子表面活性剂的制备及其界面性能
Preparation and interfacial property of quaternary ammonium organic silicon Gemini surfactant
摘要
Abstract
The epoxy group polyether polysiloxane (EPEPS) was prepared by hydrosilylation of α,ω-hydro?gen silicone (α,ω-PHMS) and al yl epoxy groups polyether (APEE) in the presence of a platinum catalyst using anhydrous ethanol as the solvent. A kind of novel quaternary ammonium organic silicon Gemini surfactant (QSGS) was synthesized by the ring-opening reaction of EPEPS with N,N-dimethyl dodecyl tertiary amine (DMA12). The chemical structures of QSGS and EPEPS were characterized by IR. The properties of QSGS, such as critical micel e concentration, surface tension, foaming power, acid, alkali and salt resistance and stabil?ity in hard water were investigated. The experimental results showed that the critical micel e concentration (cmc) of QSGS solution was 1.6 g/L, the surface tension at cmc (γcmc) of QSGS solution was 25.5 mN/m. The foaming power of 0.5% QSGS (mass fraction) solution was 1.63 and foam stability after 5 min was 0.158. The stability of QSGS in hard water was grade 5. The QSGS solution had excel ent chemical stability of acid, alkali and salt resistance.关键词
