不同类型表面活性剂对1,2,4-三氯苯的增溶作用

Solubilization of 1, 2, 4-Trichlorobenzene by Different Type Surfactants

研究了阴离子表面活性剂十二烷基硫酸钠、阳离子表面活性剂十六烷基三甲基溴化铵和非离子表面活性剂脂肪醇聚氧乙烯醚LAE对1，2，4-三氯苯（TCB）的增溶作用。讨论了表面活性剂类型对增溶作用的影响。比较发现，非离子型表面活性剂的增溶能力高于离子型表面活性剂。其原因主要是疏水有机物在非离子表面活性剂胶束中的增溶方式不同造成的。3种表面活性剂对TCB的增溶数据还表明，增港作用不仅在临界胶束浓度（MC）以上发生，而且在表面活性剂浓度低于CMC时亦有明显的增溶作用。

The solubilization of 1, 2, 4-trichlorobenzene by sodium dodecyl sulfate, cetyltrimethyl ammonium bromide, and a alkyl polyethoxyl ether LAE was studied. Effect of surfactant type on the solubilization was discussed. The solubilization power of non-ionic surfactant is higher than that of ionic surfactants. The difference is caused by difference in solubilization position of organic compound in micelles. The solubilization data reveal that the solubilization effects of surfactants are not only appeared above CMC, but also appeared below CMC.
