Abstract In this paper, quaternary phosphnium salt based magnetic ionic liquids (MILs) with different carbon chain length of cation structures selected to be studied are tetra-n-butylphosphonium ([P4444]FeCl4) and tri-n-butylteradecylphosphonium ([P44414]FeCl4). Interaction with cetyltrimethyl ammonium bromide (CTAB) or sodium bis(2-ethylhexyl) sulfosuccinate (AOT) is studied in aqueous/nonaqueous solution, respectively. Micelles formed with CTAB in aqueous solution and microemulsion formed with AOT in cyclohexane were tested and analyzed by conductance method. The results show that[P4444]FeCl4 cannot interact with surfactants in both aqueous and nonaqueous solutions. However,[P44414]FeCl4 with longer carbon chain, its properties are different from surfactants in aqueous and nonaqueous solutions. It didn't interact with CTAB in aqueous solution. However, its properties in microemulsion system formed by AOT/cyclohexane/water weren't as same as those in aqueous solution. To some extent, interaction between[P44414]FeCl4and AOT in oil-water interface would facilitate miniemulsion polymerization.
