摘要：以异构十三烷基聚氧乙烯醚-5（E1305）为表面活性剂，分别以柴油和 350~395、395~450、450~500 ℃
馏分油为油相，考察了正丁醇用量和油水体积比（简称油水比，下同）对不同油相的微乳液相行为的影响。
结果表明，随正丁醇用量的增加，微乳液体系相态由 WinsorⅠ型→WinsorⅢ型→WinsorⅡ型转变。油相馏
程温度升高，体系的最佳增溶参数降低而最佳醇度升高。对于正丁醇及 E1305 含量较低体系，随着油水比
的增大，相态发生由胶团溶液类→类 WinsorⅡ型→WinsorⅣ型→WinsorⅠ型转变。对于正丁醇含量较低且
E1305 含量较高体系，随着油水比的增大，相态由胶团溶液直接转变为 WinsorⅠ型微乳液。对于正丁醇含
量较高体系，随着油水比的增大，相态均由 WinsorⅡ型→WinsorⅢ型→WinsorⅠ型转变，发生相转变所需的
油水比与表面活性剂含量和油相的馏程温度相关。

Abstract: The effects of n-butanol dosage and oil/water volume ratio (oil/water ratio) on the phase behavior
of microemulsions, using diesel oil and distillate oil at 350~395, 395~450 and 450~500 ℃ as oil phase and
isoctylpolyoxyethylene ether-5 (E1305) as surfactant, were investigated. The results showed that the phase
of microemulsion system changed from WinsorⅠ→WinsorⅢ→WinsorⅡ as n-butanol dosage increased.
The optimum solubilizing parameter decreased while the optimum alcoholicity increased when the
distillation temperature of oil phase increased. When the oil/water volume ratio increased, the phase of
system with low content of both n-butanol and E1305 changed from micelle solution type→Winsor-likeⅡ
→WinsorⅣ→WinsorⅠ, the phase of the system with lower n-butanol content but higher E1305 content
changed directly from micelle solution to WinsorⅠmicroemulsion, and that of system with higher
n-butanol content changed from WinsorⅡ→WinsorⅢ→WinsorⅠ. The oil/water ratio required for phase
transformation was related to the surfactant content and the distillation temperature of the oil phase.
Key words: surfactants; distillate oil; microemulsion; oil/water ratio; phase behavior
