| 摘 要： | 乳状液按其颗粒大小可分为普通乳状液（约IN10pm，微小乳状液（01～0·4Pm），微乳状液（001卜0．lPm）．其中微小乳状液比普通乳状液颗粒小，分散均匀，稳定性好，比微乳状液所需乳化剂的用量要低得多，在实际应用中很有前景．但有关微小乳状液的研究工作做得很少［’－‘］．在乳化过程中，若不需外界做功，靠乳化剂的自身作用，使两种不相混溶的液体自动混合，生成乳状液称为自发乳化，无需专门的乳化设备即可方便地制备出乳状液．目前自发乳化所得的乳状液颗粒都较大，稳定性较差卜一＼若将微JJ、乳状液的制备与其自发形成的条件结合…

| Abstract: | Miniemulsions were prepared using mixed emulsifiers comprising of fatty alcohols ROH (C5OH-C16OH) and ionic or noinonic surfactants in low concentration.As a cosurfactant, fatty alcohol served as an aid for decreasing the interfacial tension and increasing the lifetime of oil drops at the oil-water interface. The mixed emulsi fier R(EO)12-NP(EO)2-ROH(R=C5-C8) could spontaneously form O/W miniemulsion in kerosene-water system. |
