Abstract：

When　a　quaternary　ammonium　surfactant　has　a　suitable　solubility　in　a　polar　solvent,　it　can　induce　the　phase　self-separation　of　mutually　soluble　polar　and　apolar　mixed　solvents　and　a　stable　interface　between　the　two　phases　can　be　formed.　This　phenomenon　is　attributed　to　the　quaternary　ammonium　surfactant　reaching　suitable　solubility　in　the　polar　solvent　and　driving　out　the　most　part　of　the　apolar　solvent　in　which　the　surfactant　is　insoluble.　As　a　result,　phase　separation　appears.　Using　aqueous　surfactant　two-phase　as　reference,　we　suggest　that　it　be　termed　nonaqueous　surfactant　two-phase　and　also　as　two　oil　phases　for　short.　©　2006　Chinese　Chemical　Society　and　College　of　Chemistry　and　Molecular　Engineering,　Peking　University.
