1. An ionic liquid is a salt in which the ions are poorly
coordinated, which results in these solvents being liquid below
100°C, or even at room temperature

2.  The methylimidazolium and pyridinium ions have proven
to be good starting points for the development of ionic
liquids:

4.  The discovery date of the "first" ionic liquid is
disputed, along with the identity of its discoverer.
 Ethanolammonium nitrate (m.p. 52–55 °C) was
reported in 1888 by S. Gabriel and J. Weiner.]

5. 1. Poor Conductors
2. Non-Ionizing
3. Highly viscous
4. Low vapour pressure
5. Low Combustibility
6. Solvating Properties

6.  High ionic conductivity
 Non-flammable
 Non-volatile
 High thermal stability
 Wide liquid range (-40ºC to 200ºC)
 Good solvents for many organic and inorganic
material.

7. Gas Handling:
Ionic liquids are attractive in gas storage
and handling applications, because of their low vapor
pressure, thermal stability, and solvation for a wide
variety of compounds and gases.

8. Recognizing that approximately 50% of commercial
pharmaceuticals are organic salts, ionic liquid forms of
a number of pharmaceuticals have been investigated.

9. ILs are potential heat
transfer and storage media in solar thermal
energy systems.

10. ILs can aid the recycling of synthetic goods,
plastics and metals.

11.  ILs can replace water as the electrolyte in
metal-air batteries.
 ILs are attractive because of their low vapor
pressure, increasing battery life by drying
slower

12.  Ionic liquids have been proposed as
an absorbent in carbon capture.
 They have various advantages over traditional
absorbents, such as the currently dominant
amine-based technologies
