And significantly reduce the interfacial tension, and through the interface state, thus produce wetting, sparkling, emulsification, compatibilizers material called surfactant. Gemini surfactants (Gemini surfactant), is a kind of water-based with two close, two hydrophobic chains and a spacer play compounds. This dissertation contains literature review and experimental two parts Review first discusses the concept of surfactant, molecular structure, performance, classification and use, through to the ordinary surface active agent, the study found that ordinary surfactant still has some flaws, a new type of surfactants is imminent. Gemini surfactants is today several years of hot topics, so the reviews of the second aspect have detailed describe Gemini surfactants structure, characteristics, classification and synthesis method. Finally to sulfonic acid salt type Gemini surfactants do with meticulous, this paper introduces the synthesis of alkyl sulfonate is the type of Gemini surfactant. The second part is part of the experiment. The experiment has written a hard ester synthesis of carbonyl chlorides and separation, among the synthesis and separation, product experiments are obtained carbonyl chlorides and hard ester synthesis product among the best conditions, and calculated the production rate, so as to prove the feasibility of the experiment scheme and advanced.
