摘要
研究了糖苷类表面活性剂C8/10烷基糖苷(APG)、C12/14醇醚糖苷(AEG)和C12/14醇醚糖苷柠檬酸单酯二钠盐(AEG-EC)与双癸基二甲基氯化铵(DDAC)复配体系的物化性能和相行为。结果表明,APG/DDAC体系的表面张力、泡沫性能和乳化性能有增效作用,润湿性能无增效作用。AEG/DDAC体系的泡沫性能和乳化性能有增效作用,润湿性能无增效作用。AEG-EC/DDAC体系的表面张力和润湿性能有增效作用,泡沫性能无增效作用。用偏光显微镜研究了三元体系的相行为,结果表明,随着DDAC含量的增加,糖苷类表面活性剂/DDAC/水体系的三元相图依次出现胶束相、胶束-液晶共存相和层状液晶相。
The properties and phase behavior of different glycoside-based surfactant/didecyldimethyl ammonium chloride （DDAC） mixtures have been investigated. The three glycoside-based surfactants are deeyl glycoside （APG）, dodecyl ethoxy glycoside （AEG） and disodium dodecyl ethoxy glycoside citrate （AEG-EC）. For APG/DDAC, synergism was observed in surface tension, foaming and emulsifying properties, not in wetting ability. For AEG/DDAC, synergism was observed in foaming and emulsifying properties, while the wetting ability exhibited no such effect. The surface tension and wetting ability of AEG-EC/DDAC mixed systems showed synergism, while the foaming property not. Phase behavior of the glycoside-based surfactant/DDAC/water ternary system has also been carried out by polarized optical microscope. The phase diagrams are characterized by a micellar phase, a region of coexistence of lamellar and micellar phases and a lamellar phase.
