Performance Study Of Anion Gemini Surfactant Derived From Cyanuric Chloride

Currently，Surfactant research focused on two aspects：First, study the relationshipbetween structure and properties for synthesis of new surfactants：First, through the existingsurfactant compound for superior application performance. Six novel Alkyl Sulfonate GeminiSurfactants was synthesized by Synthetic route of our group,Study the performance of sixGemini Surfactants with its single-chain Surfactants , Investigated the influence of thehydrophobic chain and the spacer group to the surface chemical properties and chemicalproperties of the compound system; Solubilization of benzene Anionic Gemini surfactant,Gemini Surfactants and its single-chain surfactants system; Study the liquid crystal texture ofthe Gemini surfactant solution observate of the phenomenon of the formation of vesicles ofthe Gemini surfactant solution and cetyl trimethyl ammonium bromide .The surface tension vs log molar concentration plots have been obtained by the ringmethod at temperature of 25℃. From the plots , obtained the surface properties, such ascritical micelle concentration ,surface excess concentration,Γmax, average minimum area permolecule, Amin, and figured out that it have better surface properties in anionic Geminisurfactants with single-chain surfactants. The results have been evaluated by using the regularsolution theory, and find synergism.solubilization.of Single Gemini surfactants and single-chain Surfactants complex system ,the rheological properties , lyotropic liquid crystal of the single Gemini surfactant are studied ;Observed vesicle morphology formed by Gemini Surfactants with CTAB. The results showthat: Gemini surfactant solubilization capacity increases with hydrophobic chain lengthgrowth; The increase solubilization capacity of C₈-s-C₈ （s=2,3,4,6）increased with the lengthof the spacer growth; Large amount of dissolved C₁₂-2-C₁₂and single-chain Surfactantscomplex system than the increase of the single-chain Surfactants; Gemini surfactant solution,the viscosity of the molecular structure （hydrophobic spacer length） of its aqueous solutionhas a similar contribution; Aqueous Gemini surfactants C₆-2-C₆, C₈-2-C₈, C₈-3-C₈,C₈-4-C₈,C₈-6-C₈, C₁₂-2-C₁₂solution form lyotropic liquid crystals when their mass fraction of 42.3%, 37.8%, 33.5%, 30.4%, 27.6%, 20.3% respectively; 0.01mol/L aqueous Gemini surfactantsC₆-2-C₆,C₈-2-C₈,C₈-3-C₈, C₈-4-C₈, C₈-6-C₈, C₁₂-2-C₁₂solution can not form vesicles alone,but Aqueous solution of the compound system to produce a large number of vesicles whenC₁₂-2-C₁₂/ CATB=8/2 or 9/1.The emulsification stability, the wetting ability and the lime soap dispersing power ofmixed solutions of this Gemini surfactants with single-chain Surfactants were researched,These types of complex system has a good application performance。...
