| 摘 要： | 用乳化法分离出Ｐｒｅａｌｐｉｎｅ地区油中的天然表面活性剂，将它分散到液体石蜡中，测定了该分散液的表面张力，界面张力。考察了盐度水相ＰＨ值对界面张力的影响。另外，还以此分散液制备了一些太液，比较了它们的稳定性，了盐度和水相ＰＨ值对状液稳定性的影响。

| Abstract: | Natural surfactants in crude oil(Prealpine)were isolated by emulsification. Dispersion liquids were made by dispersing the surfactant into liquid wax for surface and interfacial tension measurements.Effects of surfactant concentration and pH value on surface tension data were discussed.On the other hand,paraffin emulsions were prepared and their stability was observed.Experiments showed that saltness of the solution caused less effects on interfacial tension but more effects on the stability of paraffin emulsions containing natural surfactant. |
