摘要: 以三聚氯氰、氨基乙磺酸、乙醇胺和二正己胺、二正辛胺以及二异辛胺为原料合成出3种疏水结构不同的含羟基-磺酸基不对称表面活性剂(XSOHC6,XSOHC8和XSOHEC8),并用1HNMR,ESI-MS和元素分析对终产品进行了结构表征,结果与目标结构一致。采用吊片法测定目标产物的表面活性,运用稳态荧光探针法测定3种表面活性剂的临界胶束聚集数(Nm)。30 ℃下,XSOHC6,XSOHC8和XSOHEC8的cmc依次为8.1×10-4,2.1×10-6和8.5×10-5 mol·L-1cmc分别为33.0,27.6和28.2 mN·m-1,Nm分别为18,11和18。结果表明此类表面活性剂均具有较好的表面活性。

Abstract: Three dissymmetric surfactants containing a sulfonic and a hydroxyl group with different length of carbon chain (XSOHC6,XSOHC8 and XSOHEC8) were synthesized with cyanuric chloride,three different kinds of fatty amine,taurine and ethanolamine as starting materials.Structure of the targeted products was characterized by 1HNMR,ESI-MS and elemental analysis.Surface activity of the surfactants was measured by Wilhelmy plate method.The critical aggregation number of micelle (Nm) was determined by steady-state fluorescence probe method.The cmc of XSOHC6,XSOHC8 and XSOHEC8 is 8.1×10-4,2.1×10-6 and 8.5×10-5 mol·L-1cmc of them is 33.0,27.6 and 28.2 mN·m-1,and Nm of them is 18,11 and 18 respectively.The results of the study showed that such dissymmetric surfactants have rather good surface activity.

Key words: dissymmetric anionic surfactant, surface activity, aggregation number of micelle
