| 摘 要： | 以N,N-二甲基十二烷基胺和3-氧杂-1,5-二溴戊烷为原料合成了以3-氧杂戊基为联接基团的季铵盐型双子表面活性剂。产物的结构用红外光谱和核磁共振氢谱进行表征。测定了25℃下双季铵盐水溶液及其与NP-6、NP-8、NP-15、AEO-3的二元复配体系的表面张力。结果表明,与传统单链表面活性剂相比,双季铵盐表面活性剂具有更为优异的表面活性;每一种二元复配体系都具有显著降低表面张力的协同增效作用。与传统杀菌剂1631(十六烷基三甲基溴化铵)相比,双季铵盐表面活性剂具有更为优异的杀菌抑菌性能,其中对苹果轮纹菌、小麦赤霉菌的杀菌抑菌作用最佳。考察了弱碱性介质中双季铵盐水溶液及其复配体系对锌的缓蚀作用,结果表明:当pH值为8,双季铵盐水溶液的浓度低于20 mg/L时对锌具有较好的缓蚀作用,而高于此浓度时的缓蚀效果明显下降并表现出一定的腐蚀作用;在复配体系中,双季铵盐与NP-15的1∶1二元复配体系对锌的缓蚀作用最好。

| Abstract: | Quaternary ammonium salt Gemini surfactant with 3-oxa pentyl being conection groups was produced by reaction of N,N-dimethyl-dodecyl amine and 3-oxa-1,5-dibromo pentane.The structure of target product was verified by IR and 1HNMR spectroscopy.Surface tention of biquaternary ammonium salt aqueous solution and its binary complex systems with NP-6,NP-8,NP-15,AEO-3 were measured.The results showed that,compared with conventional surfactants,biquaternary ammonium salt had better surface activity and each of bina... |
