Application Of Interaction Between Amphiphilic Molecular Ionic Liquids And Surfactants

Ionic liquids have overcome sorts of disadvantages of traditional organic solvents.There is great potential to be designability solvent.The amphiphilic ionic liquids,which combined with designability and amphiphilic structure is an emerging substance that accords with the"green chemistry"concept.Tetrabutylphosphine chloride ferric chloride and tetradecyl tributylphosphine chloride ferric chloride（[P4444]FeCl₄ and[P44414]FeCl₄）are the amphiphilic ionic liquids in this work.The effect of the interaction between[P4444]FeCl₄（[P44414]FeCl₄）and cetyltrimethylammonium bromide（CTAB）on cmc（CTAB）are studied in in aqueous solution.It turned out that[P4444]FeCl₄（[P44414]FeCl₄）forming micelle by aggregation.Neither did interact with CTAB nor effect the value of cmc.Adding to[Bmim]Cl、[P4444]FeCl₄ and[P44414]FeCl₄ into the AOT/cyclohexane system,ionic liquid microemulsion will formed.Ionic liquids would affect the properties of oil-water interface membranes;the effect of temperature on ionic liquid microemulsion was studied by conductivity method.The influence of ionic liquid concentration and water content（W₀）on the change of percentage content of solubilization water in different states was studied by infrared method.The way of action of three ionic liquids was obtained.The particle size analyzer measures the particle size distribution of the microemulsion formed by different concentrations of ionic liquid.The traditional surfactant aqueous two-phase system and the ionic liquid/salt aqueous two-phase system have good performance in extraction tryptophan.Furthermore,at a certain ratio（ionic liquid:surfactant）and salt concentration,a new type of ATPS were obtained（[P4444]FeCl₄（[P44414]FeCl₄）/SDS（SDBS）/sodium citrate）.So does[Bmim]Cl.while using[Bmim]Cl as a reference.The aggregation of the top and bottom phases was studied by polarized light microscopy.The top phase was found to be liquid crystal state,and xylenol orange disodium salt was extracted into the top phase.This study not only helps to fill gaps in the interaction of quaternary phosphonium salt ionic liquids with surfactants,but also contributes to the adjustment states of solubilization water in microemulsions,providing them theoretical support as nanoreactors and biofilm models.
