Synthesis And Evaluation Of Dual-carboxylic Acid Ester, Sodium Tartrate Series Of Gemini Surfactants

Oigomeric surfactant is a new type of surfactant which link two or more conventional surfactant by the space group This dissertation introduce the characteristic of the structure,progress of the rearch,properties,application of the oigomeric surfactant. And synthesize a series of Gemini J by tartaric acid and longchain carboxylic acid,and verify the structure of GeminiJ. Measure the surface tension of different consistency of Gemini J and conventional carboxylate surfactant,and drawthe figure of surface tension surve of Gemini J and conventional carboxylate surfactant.Rearch the influence and reason of inflence from space groupl and lyophobic chain.Rearch the interface properties of the synergism between Gemini J and conventional cationic surfactants DTAB.
