Abstract:

As one of the new anionic surfactants, sulfonated Gemini surfactants are formed by combining two or more sulfonated surfactants monomer via space groups through covalent bonds. They show potential applications in industry due to their improved properties such as higher surface activity, less critical micelle concentration(cmc), better washing ability, excellent blending performance with conventional anionic surfactants, unique rheologic behavior, good anti-salinity and so on. In this paper, the synthetic methods of a series of sulfonated Gemini surfactants are briefly reviewed according to the origin of the raw materials and the research direction on the synthesis of sulfonated Gemini surfactants is speculated.

Key words: sulfonate, Gemini surfactants, synthesis, progress
