摘　　要：绘制了２９８Ｋ下三正辛胺盐酸盐（ＴＯＡ·ＨＣｌ）－正庚烷（Ｃ７Ｈ１６）－水（Ｈ２Ｏ）体系的三元相图．富盐相中分子的有序聚集均为层状排列．这种层状结构中，盐对水和正庚烷的饱和增溶量为ＴＯＡ·ＨＣｌ：Ｈ２Ｏ：Ｃ７Ｈ１６＝１：２：３（摩尔比）．ＴＯＡ·ＨＣｌ的表面性质和增溶能力决定了体系的相行为．在整个范围内未发现有球状或其它形状聚集体的生成．The phase diagram of the TOA·HCl- n -heptane-H 2O system at 298 K is reported The phase behavior of this system is controlled by the amphiphilic properties of TOA·HCl salt The solubilization capacities with water and n -heptane in the ordered lamellar structure are within TOA·HCl:H 2O: n -C 7H 16 =1:2:3 (molar ratio) The lamellar structure of salt-rich phase is not destroyed when a new phase is formed No spherical or other geometric aggregations are found in the range under investigation
