摘　　要：以环己烯二甲酸二甲酯、N,N-二甲基-1,3-丙二胺、溴代十四烷为原料合成了一种新型双子阳离子表面活性剂十四烷基环己烯基二甲酰胺类双季铵盐(KB-14),测定了其表面性质。以邻苯二甲酸二甲酯为增溶对象,探索了KB-14、十二烷基硫酸钠(SDS)、十六烷基三甲基溴化铵(CTAB)、烷基酚聚氧乙烯醚(OP-10)的增溶效果以及添加聚乙二醇-10000(PEG-10000)对增溶效果的影响。结果表明:KB-14、OP-10、CTAB、SDS对邻苯二甲酸二甲酯的摩尔增溶比(MRS)分别为0.82、0.33、0.29、0.09,添加PEG-10000对KB-14、CTAB有增效作用,对SDS影响不明显,而对OP-10具有禁阻作用。A new cationic Gemini surfactant of tetradecyl cyclohexenyl dimethyl formamide bis quaternary ammonium salt（KB-14）was synthesized using dimehtyl cis-1,2,3,6-tetrahydrophthalate,N,N-dimethyl-1,3-propyldiamine,and 1-bromotetradecane as strating materials and its surface properties was determined.The solubilization capacity of KB-14,sodium dodecyl sulfate（SDS）,N,N,N-trimethyhexadecan（CTAB）,and octylphenol polyoxyethylene ether（OP-10）on dimethyl phthalate were examined and the additive effect of polyethylene glycol-10000（PEG-10000）was also investigated.The results showed that the molar solubilization ratio（MSR）of KB-14,OP-10,CTAB,and SDS to dimethyl phthalate are 0.82,0.33,0.29,0.09,respectively.The addition of PEG-10000 into KB-14 and CTAB presents the strong synergism while SDS shows no obvious influence and OP-10 inhibits the solubilization effect.
