摘要
考察了助表面活性剂与表面活性剂的质量比(m2)、丙烯酸(AA)、丙烯酰胺(AM)、表面活性剂和氧化还原引发剂(NH4)2S2O8-NaHSO3等多种因素对CTAB(SDBS)/正戊醇/石油醚/水体系溶水量的影响,首次探明了以石油醚为油相的微乳液形成的较适宜条件,结果表明:对于CTAB微乳液体系,m2在0.6～2.5能形成微乳状液,而对于SDBS微乳液体系,m2仅在0.3～1.5能形成微乳状液;加入适量单体AA、AM和氧化还原引发剂(NH4)2S2O8-NaHSO3可以提高溶水量.
Effects of the mass ratio of cosurfactant to surfactant（m2）, as well as the amount of acryhc acid, acrylamide and redox initiator （NH4）2S2O8- NaHSO3 on the water solubilization performance of microemulsions CTAB（SDBS）/n - pentanol/ petroleum ether/water system were examined. The suitable conditions for the formation of microemulsions based on petroleum ether as oil phase were found. Experimental results showed that the petroleum ether - based microemulsions can be formed with the value of m2 within 0.6 - 2.5 and 0.3 -1. 5, using CTAB and SDBS as the surfactant respectively. The water solubilization performance of the prepared microemulsions can be enhanced by adding a suitable amount of acrylic acid, acrylamide and redox initiator.
