双联(Gemini)两性表面活性剂的复配性能研究

Effect of the Combination Performance of Zwitterionic Gemini Surfactant

合成了一种新型双联(Gemini)两性表面活性剂-乙二醇双琥珀酸一氯羟丙基季铵双酯磺酸钠(HDBC).同时研究了HDBC与其它表面活性剂的在表面张力上的协同效应.结果表明:HDBC与十二烷基硫酸钠(SDS)质量比为5:5时,协同增效作用最佳.以最佳比例复配后,使用量为0.5g/L,表面张力达到35.61 m N/m.而HDBC或SDS在浓度为0.5g/L时,各自的表面张力为44.89、41.56m N/m,复配后大大降低了表面张力.

In the presence of a novel kind of zwitterionic Gemini surfactant,sodium 1,2-ethanediol bisulfosuccinate hydroxypropropyl quaternary ammoniun diester(HDBC)was synthesized.And synergistic surface tension effect of HDBC and sodium dodecyl sulfonate(SDS)was also studied.It was showed that there was excellent on synergistic effect between HDBC and SDS.There was a best surface tension as WHDBC:WSDS=5:5,the surface tension was 35.61 mN/m under the dosage of 0.5g/L.When the concentration of HDBC or SDS is 0.5g/L,the surface tension is 44.89、41.56mN/m respectively.After HBD and SDS are combined,the surface tension is reduced extremely.
