Synthesis of anionic sulphonate-crown ether surfactants
摘要:
Two sulphonate-crown ether surfactants (sodium (4'-dodecanoyldibenzo-18-crown-6)-4 ''(5 '')-sulphonate, 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, H-1 NMR and elemental analysis. The physicochemical properties of the surfactants were studied by fluorescence, conductivity and dynamic light scattering techniques. (C) 2013 Qing-De Chen and Xing-Hai Shen.
