| 摘 要： | 以石油中间产品为原料，合成了烃基苯磺酸盐表面活性剂ＡＳ－４。考察了盐浓度，碱浓度和ＡＳ－４ 浓度对ＡＳ－４ 水溶液与原油体系的动态界面张力的影响。结果表明，当Ｎａ２ＳＯ４ 浓度为５～１５ｇ／Ｌ，ＮａＯＨ 浓度为５～１０ｇ／Ｌ，ＡＳ－４ 浓度为０．１～０．５ｇ／Ｌ的条件下，ＡＳ－４ 水溶液与原油体系的动态界面张力具有１０－ ３ｍ Ｎ／ｍ 以下的超低最小值。还研究了ＡＳ－４ 表面活性剂的组成（不同的异构体）对其水溶液与原油体系的动态界面张力的影响。

| Abstract: | Using Intermediate product of petroleum as original reagent,the hydrocarbon phenyl sulfonate surfactant,named as AS 4,has been synthesized.The effects of the concentration and composition of AS 4 on the dynamical interfacial tension of AS 4/alkali/crude oil system at different salinities,alkalinitise were examined and discussed.The result shows that when salinity is in 5~15g/L Na 2SO 4, alkalinity in 5~10g/L NaOH,surfactant AS 4 concentration in 0.1~0.5g/L,AS 4/alkali/crude oil system has ultra low minimum interfacial tension of less than 10 -3 mN/m. |
