  • Hujun Xu , Peng Kang and Xinyan Bao


Gemini surfactant, N,N′-bis(dimethyl ethyl dodecane)ethyl ether dibromide was synthesized and symbolized as II-12-EO2. The surface chemical properties and micelle behaviors of II-12-EO2 with poly (ethylene oxide) (PEO) lauryl ether (C12E6) and sodium dodecyl sulfate (SDS) were investigated in 0.1 mol · L−1 sodium bromide aqueous solution at 313 K using surface tension measurements and steady-state fluorescence spectroscopy. The critical micelle concentration (cmc) of II-12-EO2 is 1.99 × 10−4 mol · L−1 and the aggregation number is 23. The cmc values of the two binary systems with different molar fractions are all lower than those of pure constituent surfactants, and the aggregation numbers of the binary systems are all larger than that of II-12-EO2. The interaction parameters β of the two binary systems were calculated, and the negative values of β indicate the existence of synergism in surface tension reduction efficiency, mixed micelle formation and surface tension reduction effectiveness.


Es wurde das Gemini-Tensid N,N′-Bis(di-methylethyldodecan)ethyl-etherdibromid synthetisiert und als II-12-EO2 bezeichnet. Die chemischen Oberflächeneigenschaften und das mizellare Verhalten von II-12-EO2 mit Poly(ethylenoxid)(PEO)laurylether (C12E6) und Natriumdodecylsulfat (SDS) in wässriger 0,1 mol/L Natriumbromidlösung wurden bei 313 K mittels der Messung der Oberflächenspannung und der stationären Fluoreszenzspektroskopie untersucht. Die kritische Mizellbildungskonzentration (cmc) von II-12-EO2 beträgt 1,99 × 10−4 mol · L−1, die Aggregationszahl ist 23. Die cmc-Werte der beiden binären Systeme mit unterschiedlichen Molenbrüchen sind kleiner als die der reinen Komponenten. Die Aggregationszahlen der binären Systeme sind höher als die von II-12-EO2. Es wurde die Wechselwirkungsparameter β der beiden binären Systeme berechnet. Die negativen β-Werte deuten auf Synergismen bei der Reduktion der Effizienz der Oberflächenspannung, bei der Bildung von Mischmizellen und bei der Abnahme der Effektivität der Oberflächenspannung hin.
