利用净平均曲率模型重现了以十二烷基硫酸钠( SDS)为表面活性剂,正丁醇和正戊醇为助剂,短碳链烷烃的相行为和增溶参数的变化情况。模拟了Winsor相图及最佳增溶参数曲线,并和实验进行了对比,与实验结果吻合的较好,并且发现在相同表面活性剂和助剂下,油越轻,增溶量越大,采用正戊醇做为助剂增溶轻油的能力约为采用正丁醇的3倍。在表面活性剂用量相差不大,助剂量相同的情况下,出现中相所需的盐度都是正己烷<正庚烷<正辛烷<正十二烷,以正戊醇为助剂所需的盐度远小于以正丁醇为助剂所需的盐度。

The average net curvature model was used to simulate the phase behavior and solubilization parameters of dodecyl sodium sulfate( SDS) microemulsion systems, with n-butanol or n-pentanol as cosurfactant and short carbon paraffins as light oil. Winsor phase diagram and the optimum solubilization parameter curve are simulated,and the experimental results were compared with the data predicted from the model. The simulating results fit well with the experimental data. It was found that for microemulsions with the same surfactant and co-surfactant,the lighter is the oil,the greater will be the amount of solubilized. The solubilization capacities for microemulsions’systems using pentanol as cosurfactant are about three times of those using n-butanol as cosurfactant. When simi-lar amount of surfactant and cosurfactant are used,all of the microemulsion systems show similar tendency,that is,the desired salini-ties for the systems should be hexane<heptane<octane<dodecane,and the desired salinities for the systems using n-pentanol as co-surfatant should be far less than that of n-butanol.
