Study on Foam Properties of Alkylbenzene Sulfonate Gemini Surfactants

Abstract:

Foamability and foam stability of alkylbenzene sulfonate Gemini surfactants solution were studied with Ross-Miles method. The variations of foamability and foam stability with concentration, Hydrophobic group and temperature were studied, respectively. It was found that foamability begins to increase with increment of concentration, when concentration increases to a degree, foamability no longer increases. And foamability decreases with increment of alkyl length in the whole concentrations. The stability of surfactants begin to increase with increment of concentration. When concentration is increased to 0.5 g/L, the stability begin to decrease. And the stability of Ic is much better than that of Ia. Furthermore, the foamability of Ia and Ic increases with temperature, however the foam stability of them decreases with temperature.
