Structure-property relationship study of room temperature ionic liquids

Project goals

Ionic liquids are a novel class of material with a potential use in an extraordinary wide range of chemical, engineering and materials applications. The effect will be studied of pressure and of variations of the anion and the cation of ionic liquids ontheir volumetric properties from the melting curve to 363 K in temperature and up to 60 MPa in pressure. Density measurements will be performed on nine imidazolium based ionic liquids with tetrafluoroborate, dicyanamide and trifluoromethanesulonate anionalso in the sub-ambient temperature region that has not yet been measured at all. An apparatus will be used making possible measurements down to 183 K. The exp. uncertainties of temperature, pressure and density should not exceed plus-minus 5 mK, plus-minus 0.015% and plus-minus 0.1%, respectively. Current models for predicting volumetric prop. of ionic liquids will be tested based on density, volume expansivity and isothermal compressibility evaluated from the obtained data using Tait equation.

    Studium závislosti vlastností iontových kapalin na jejich struktuře

  • Annotation in Czech

    Iontové kapaliny představují novou třídu látek s mimořádně širokým spektrem perspektivních aplikací nejen v oblasti chemie, ale také technických a materiálových. Bude zkoumána závislost volumetrických vlastností iontových kapalin na tlaku a na jejich aniontu a kationtu v oblasti teplot od křivky tání do 363 K a pro tlaky do 60 MPa. Budou provedena měření hustoty devíti imidazolových iontových kapalin s anionty [BF4], [N(CN)2] a [CF3SO3] a to i v dosud zcela neprozkoumané oblasti teplot pod běžnou teplotou okolí. Bude použita aparatura umožňující měření již od 183 K. Exp. nejistoty teploty, tlaku a hustoty nepřesánou hodnoty plus-minus 5 mK, plus-minus 0.015% a plus-minus 0.1%. K vyhodnocení objemové roztažnosti a izotermické kompresibility iontových kapalin bude použita Taitova rovnice. Na získaných datech budou testovány současné prediktivní modely pro volumetrické vlastnosti iontových kapalin.

  • Project results evaluation

    Using two apparatuses, one of which was constructed within the project, selected thermodynamic properties were measured of eight still poorly investigated ionic liquids and the dependence of these properties on the ionic liquid structure was analyzed.
