چکیده انگلیسی
The effect of temperature on the interfacial tension between gemini surfactant solution and crude oil is investigated in this paper. The interfacial tension is measured by the spinning drop interfacial tension-meter of Texas-500c. For surfactants 14-4-14 and 16-4-16, the interfacial tensions are very sensitive to temperature and undergo minima with the increase of the temperature. Temperature has also an effect on the dynamic interfacial tension, i.e. increasing the temperature can shorten the time needed for an interfacial tension to reach equilibrium. However, for a mixing surfactant system, the effect of temperature on the interfacial tension between oil and surfactant solution is not remarkable because of synergism.
