| Abstract: | The interfacial tension, wettability, foam and emulsification properties of di-tetrapropylene diphenyl ether disulfonates (C12-DADS) gemini-type surfactant have been studied and compared to mono-tetrapropylene diphenyl ether disulfonates (C12-MADS) and tetrapropylene benzene sulfonates (C12-BAS). The results show that the C12-DADS have a lower interfacial activity compared to that of C12-MADS and C12-BAS. The wettability of the three surfactants decreases in the order C12-BAS?>?C12-DADS?>?C12-MADS. For foam properties, the foamability and foam stability of C12-MADS and C12-DADS is lower than that of C12-BAS. In addition, the emulsification ability increase in the order C12-DADS?12-MADS?12-BAS. |
