摘要：合成了不溶于水的季铵盐型Gemini表面活性剂18-s-18(=3,4,6,8,10,12),研究了联结基团长度对Gemini表面活性剂在气液界面上的性质的影响。结果表明:对不同长度的联结基团,表面压-分子面积曲线很相似;极限面积在s≤6时几乎成直线快速增加,并在s=10时达到最大值,s>10时稍微下降。
The insoluble cationic bis-（quaternary ammonium halide） surfactants（Gemini）,abbreviated as 18-s-18（s=3,4,6,8,10,12）,were synthesized,and their surface properties at the air/water interface were investigated.For the Gemini surfactants with different spacer length,it was found that the surface pressure-molecular area isotherms resembled each other.The limiting area increased rapidly and almost linearly with the increase of spacer length for the short spacers,but reached a maximum as s=10 and ther decreased slightly at s10.
