摘　　要：Two sulphonate-crown ether surfactants （sodium （4＇-dodecanoyldJbenzo-18-crown-6）-4＂（5＂）-sulpho- nate, ammonium （4＇-dodecanoyldibenzo-18-crown-6）-4＂（5＂）-sulphonate） were designed and synthesized via a two-step continuous method. The products were purified 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.Two sulphonate-crown ether surfactants （sodium （4＇-dodecanoyldJbenzo-18-crown-6）-4＂（5＂）-sulpho- nate, ammonium （4＇-dodecanoyldibenzo-18-crown-6）-4＂（5＂）-sulphonate） were designed and synthesized via a two-step continuous method.
