Open publisher page 0 citations

Abstract

The basic surface activities of sulphonated Oil SS were characterized,which included these items such as critical micelle concentration (CMC),surface tension of surfactant,Krafft temperature,sensitivity to calcium ion (Ca2+),influence of pH and Na+ on surface tension,and the emulsification activity to oil of animals and plants. The result shows that the sulphonated oil SS has better stability in hard water,little influence of pH on critical micelle concentration and surface tension,and better capability of electrolyte -resistant and emulsification. At 20 ℃ ,it is measured that the critical micelle concentration of sulphonated Oil SS is 0.1364-0.1494 g/mL,and the Krafft temperature is 21.6 ℃. The surface tension of sulphonated Oil SS is higher,which has guiding significance for practical application of the sulphonated oil SS.
