中文摘要:
      【】以氯乙酰氯、1,3-丙二胺,十二烷基二甲基叔胺为原料,通过二步法合成了一种新型双子化季铵盐表面活性剂即二[2-酰胺基-3-(十二烷基二甲基季铵基)丙基]-丙胺二氯化表面活性剂。采用红外光谱(FTIR)对合成产物进行结构表征;分别将其与阴离子表面活性剂十二烷基苯磺酸钠(SDBS)和稀土元素七水氯化铈进行复配,研究复配体系对铝合金在酸性溶液中的缓蚀性能和机理。结果表明两复配体系均能产生良好的协同作用:IE(C合成产物:CSDBS=10:9)= 96.8%,IE(C合成产物:C氯化铈=10:9)= 95.5%;合成产物与SDBS复配的缓蚀机理为利用静电吸附作用在铝合金表面形成致密吸附膜;合成产物与氯化铈复配的缓蚀机理为氯化铈可先在溶液中形成配合物,该配合物进一步吸附于金属表面从而起到协同缓蚀作用。
英文摘要:
      【】 Chloroacetyl chloride, 1,3-propanediamine, dodecyldimethylamine as raw materials were taken as raw materials to synthesize a new multi-alkyl multiple quaternary ammonium salts Gemini surfactant Bis [2-amido-3-(dodecyldimethylammonio)propyl]- propylamine dichlorinated surfactant. The structure of the synthetic product was characterized by FTIR. Inhibition efficiencies and inhibition mechanisms of the synthetic product+SDBS, synthetic product+CeCl3.7H2O compound systems to aluminum alloy in hydrochloric acid solution were studied. Results indicate that, synergistic effects of two compound systems are ideal: IE(Cproduct:CSDBS=10:9)= 96.8%, IE(Cproduct:CCeCl3=10:9)= 95.5%. Synthetic product+SDBS plays a role in inhibition mainly by forming a dense adsorption film, while the synthetic product+ CeCl3.7H2O could form a complex in the solution and be adsorbed on the aluminum alloy, thus improving the inhibition effect.
