| Abstract: |
| Sodium dialkylated diphenylether disulfonate (Cn-DADS, n = 8, 10, 12) was synthesized by Friedel-Crafts alkylation of α-olefins and diphenyl oxide with solid acid as catalyst. The purity and the structure of dialkylated diphenylether were characterized by HPLC and NMR. The structure of Cn-DADS was confirmed by electrospray ionization-mass spectrometry. The surface activity,interfacial activity and wettability of Cn-DADS, as well as the effects of NaCl on these properties, were investigated. |
