| 摘 要： | 在 2 5℃测定了十二烷基硫酸钠 (SDS) /正戊醇 /水三元体系的相平衡 ,确定了液晶区域的边界范围。在液晶区域内选取一系列样品点 ,用差示扫描量热法 (DSC)和2 HNMR与液晶照片对照 ,研究了该体系的液晶结构特点。结果表明 :在恒定温度下 ,该体系存在着两个液晶区域 ,并且随含水量的增加 ,液晶结构发生变化。当组成固定时 ,体系的液晶相结构随温度升高也发生变化

| Abstract: | The equilibrium phase diagram of the sodium dodecyl sulfate (SDS)/ n C 5H 11 OH/H 2O system were determined at 25 ℃, and the polarizing microscope, 2H NMR and DSC were used for determining the structures of various samples in SDS/ n C 5H 11 OH/H 2O liquid crystalline regions. The results showed that there are 2 liquid crystalline regions in this system, the structure of the liquid crystal phase not only changed with varying the content of water at a certain temperature, but also changed with varying temperature at a certain composition. |
