摘要：

The　conductivity　properties　of　ionic　liquids　reflects　the　conductive　capacity　of　ionic　liquids,　which　is　closely　related　to　the　degree　of　ionization　in　the　solvents　and　the　ability　of　ion　solvation.　In　order　to　study　the　conductivity　of　five　synthetic　ester-substituted　imidazole　ionic　liquid　which　were　synthesized　by　our　lab,　we　used　the　DDS307　conductivity　meter　to　determine　the　conductivities　of　[MIMCH2COOCH3]NTf2,　[MIMCH2COOCH2CH3]NTf2,　[MIMCH2COOCH2CH2CH3]NTf2,　[MIMCH2C6H4COOCH3]NTf2　and　[MIMCH2C6H4COOCH2CH3]NTf2　in　the　solvents　of　methanol,　acetonitrile,　DMSO,　ethyl　acetate,　respectively.　The　results　shown　that　within　a　certain　concentration　range,　the　conductivity　of　the　ionic　liquid　increased　with　the　increase　of　the　liquid　concentration,　when　other　conditions　remained　the　same.　Moreover,　within　a　certain　temperature　range,　the　conductivity　of　the　ionic　liquid　increased　with　the　increase　of　the　temperature.　Compared　between　the　conductivities　of　the　four　solvents,　the　values　of　the　conductivities　ranging　from　small　to　large　were　in　the　order　of　ethyl　acetate,　DMSO,　methanol　and　acetonitrile.　Reflects　the　interaction　of　five　kinds　of　ester-substituted　ionic　liquids　and　the　ethyl　acetate.　©　All　Right　Reserved.
