摘　　要：采用浊点滴定法测定各组分的溶解度曲线,绘制出了正己烷-乙醇-水的三组分液系相图。结果表明,在室温为10.0℃时,正己烷-乙醇-水的三组分液系相图中,等温会溶点D点处,乙醇、正己烷的质量分数分别为73.0%、14.1%;双结点溶解度曲线BDC内,形成了两个共轭的三组分溶液;物系点O时,两共轭溶液数量的比值为m_G:m_H=|OH|:|OG|。The n-hexane-alcohol-water ternary liquid phase diagram was obtained through the solubility curves of the ternary determined by cloud-piont-titration method. It showed that at room temperature 10.0 ℃,in the n-hexane-alcohol-water ternary liquid phase diagram,at the isothermal consolute D point,the mass fraction of alcohol and n-hexane was 73.0% and 14.1%,respectively. Two conjugate ternary solutions were formed in the binodal solubility curve BDC,and at the system point O,the mass ratio of the two conjugate solutions was m_G： m_H= ｜ OH ｜ ： ｜ OG ｜.
