摘要: Friberg曾以等摩尔的三乙醇胺(TEA)与油酸(OLA)混合,生成了三乙醇胺油酸盐(TEA-OLA)非水层状液晶[1],并指出在TEA的作用下,大部分OLA去质子,生成了三乙醇胺油酸盐,组成层状液晶两亲双层,剩余的TEA、OLA作为溶剂存在于层状液晶的溶剂层中,本文报道以甲酰胺(FA)为溶剂时TEA-OLA与TEA-OLA/FA层状液晶的生成范围及其稳定性。

Abstract: Triethanolammonium oleate(TEA-OLA) liquid crystals were formed from triethanolamine(TEA) and oleic acid (OLA) in weight ratio of OLA/TEA= 60/40~75/25(molar ratio ofOLA/TEA=0.79~1.58). Both the stability of TEA-OLA liquid crystal and the solubilizingability for formamide(FA) increased with the weight ratio of OLA/TEA.
