| Abstract: |
| In this paper, using raw materials of lauric acid, chlorosulfonic acid,N,N-DMEA and bromdecane, synthesized a new type of amphiprotic gemini surfactants, i.e. α-sulfonic acid-lauryl acyl oxygen ethyl-dimethyl dodecyl ammonium bromide. And characterized the structure of the final outcome by the infrared spectrum, and evaluated the surface activity, compound property, emulsification and foamability of the synthetic |
| Key words: sulfonation, quaternization, esterification, emulsification, complex formulation, foamability |
