摘要:

随直键醇CnH2n+1OH的链长增加,Igepal CO 520/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/Igepal CO 520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Igepal CO 520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.
