在45 ℃下测定了不同类型表面活性剂(阴离子、阳离子和非离子表面活性剂以及高分子双子表面活性剂、非对称两性双子表面活性剂)与煤油-水体系的界面张力,发现非离子表面活性剂效果最好,界面张力可达0.690 mN/m。采用聚乙二醇辛基苯基醚与其他类型的表面活性剂进行两两复配,考察复配表面活性剂的种类、质量比、总质量浓度对模拟油-水体系界面张力的影响。发现聚乙二醇辛基苯基醚与非对称两性双子表面活性剂C_(15)EC-S-C_(16)以质量比7∶3进行复配,总质量浓度为50 g/L时,界面张力达到0.024 mN/m。 |

Interfacial tension of kerosene-water system with different types of surfactant (anionic,cationic and nonionic surfactant as well as polymeric Gemini surfactant and asymmetric amphoteric Gemini surfactants) was investigated and compared.Results showed that nonionic surfactant is the one which may display lowest interfacial tension of 0.690 mN/m.Ethoxylated octylphenol nonionic surfactant (OP type) was selected to be blended with different types of other surfactants to examine the effects of type of the blend surfactant and their mass ratio,as well as the overall mass concentration on the interfacial tension of the mimetic oil-water system.Results showed the blend surfactant composed of ethoxylated octylphenol and asymmetric amphoteric Gemini surfactant (C_(15)EC-S-C_(16),laboratory prepared) with mass ratio of 7∶3 and overall mass concentration of 50 g/L can reduce the interfacial tension to a minimum value of 0.024 mN/m. |
