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
