摘要

Abstract

Ionic liquid 1-methyl-3-(3-sulfopropyl)-imidazolium hydrogen sulfate([C

) was synthesized and characterized by infrared spectroscopy(IR)

nuclear magnetic resonance(

H and

C NMR) and ultraviolet-visible(UV-Vis) spectra. Its thermal stability was also examined by thermogravimetric analysis(TGA) and a differential scanning calorimeter(DSC). The mole fraction solubilities of [C

-pentane

-hexane

-heptane

benzene

toluene

ethylbenzene

acetone

2-butanone

3-methyl-2-butanone

tetrahydrofuran

ethyl acetate and dichloromethane) in the temperature range from 289.15 to 363.15 K were measured using a static analytical method and correlated with an empirical equation.
