Two sulphonate-crown ether surfactants(sodium(40-dodecanoyldibenzo-18-crown-6)-400(500)-sulphonate,ammonium(40-dodecanoyldibenzo-18-crown-6)-400(500)-sulphonate)were designed and synthesized via a two-step continuous method.The products were purifed and characterized by IR,1H NMR and elemental analysis.The physicochemical properties of the surfactants were studied by fluorescence,conductivity and dynamic light scattering techniques.
