| 摘 要： | 随直键醇CnH2n 1OH的链长增加，IgepalCO520/CnH2n 1OH/H2O体系三组分相图中层状液晶区域增加，使得W/O区域上移，W/O区域中最大水增溶量处所需摩尔比CnH2n 1OH/IgepalCO520降低，W/O区域中水的最大增溶量（摩尔分数）却不变．层状液晶中CnH2n 1OH的最佳链长为n＞8，W/O区域中CnH2n 1OH的最佳键长为n＞10，即能获得比较好的与IgepalCO520的配伍性．

| Abstract: | With increasing of n in CnH2n+1 OH, the lamellar liquid crystal region increases and W/O region moves upward in the three components phase diagram, and the maximum water content (molar fraction) solubilized in W/O region is constant but the molar ratio of CnH2m+1 OH/Igepal 520 decreases at maximum water content. The chain length of CnH2n+1 OH is n＞8 in the lamellar liquid crystal and n ＞10 in the W/O region. |
