同电性的季铵盐Gemini表面活性剂C12sC12·2Br(s=2,3,4,6)与烷基溴化铵CmTXABr在水溶液中生成了混合胶团,其行为接近理想混合,未出现协同效应(synergism)。C12sC12·2Br/C12TMABr混合体系胶团的临界胶团总浓度cmcT随s增大先增加,在s=4时出现相对最大值,然后略有下降,这种变化规律类似单组分C12sC12·2Br水溶液的胶团化行为。随着CmTMABr疏水链增长或C12TXABr季铵头基尺寸增大促进了它们与C122C12·2Br的混合胶团化,在等摩尔混合时的cmcT分别为1.30(s=2/C12TMABr)、1.25(s=2/C14TMABr)、0.96(s=2/C16TMABr)、1.27(s=2/C12TEABr)和1.21(s=2/C12TBABr)mmol/L。
Electrically quaternary ammonium salt Gemini surfactant C12sC12 · 2Br (s = 2,3,4,6) and alkyl ammonium bromide CmTXABr generated in a mixed solution of micelles, its behavior is close to the ideal mixture, there is no synergy Synergism. The critical micelle concentration (cmcT) of C12sC12 · 2Br / C12TMABr mixed micelles first increased with increasing s, then reached a relative maximum at s = 4 and then decreased slightly. The variation was similar to that of single-component C12sC12 · 2Br aqueous solution The micelle behavior. CmcT at the same molar mixing were 1.30 (s = 2 / C12TMABr) and 1.25 (s = 2 / C14 TMABr), 0.96 (s = 2 / C16 TMABr), 1.27 (s = 2 / C12 TEABr) and 1.21 (s = 2 / C12 TBABr) mmol / L.
