Thermophysical properties and ecotoxicity of new nitrile functionalised protic ionic liquids

In this present research, five nitrile functionalised imidazolium based protic ionic liquids (PILs) by varying alkyl chain length of anions were synthesized. The synthesized ILs were characterized with nuclear magnetic resonance spectroscopy (NMR) and elemental analyser (CHNS). Various thermophysica...
