Ionic Liquid
FUJI IL Series
Ionic Liquid is the new material that has been intensively underresearch and development, and commercialization. Recently,ionic liquid is defined as the material (salt : composed of 100 % ofion) that they exist as the “liquid” under 100℃. One can create
numerous numbers of material, and properties by combining
various kinds of cation and anion. Therefore, they can be regarded
as designer’s solvent. Or sometimes even referred as “the thirdliquid” following to water and organic solvent.

The feature of ionic liquid1. They stay as the liquid under wide temperature range so thatthey can be applied and utilized under high and low temperature.
2. Ionic liquid is conductive so that they can be used forelectrochemical devises and antistatic purpose.
3. Ionic liquid is chemically, electrochemically stable, also safe
under high temperature. Therefore, they can be used undervarious kinds of extreme conditions.
4. Ionic liquid can be used under vacuum condition because vapor
pressure of ionic liquid is low.
5. Ionic liquid is very safe material because they possess flame
retardant property.
6. Ionic liquid can dissolve (melt) various kinds of material including
cellulose so that numbers of application can be expected.

TECHNICAL INFORMATION

Chemical Composition
Ionic liquids are composed of organic cation such as imidazolium
ion, pyridinium ion etc… and anion including bromide, fluoride,
chloride etc… and form as the liquid under relatively low
temperature even they are 100 % ion material.

Example of Ionic Liquid

Cation1- ethyl-3-methylimidazolium (EMI)1- butyl-3-methylimidazolium (BMI)
N,N –dialkylpyrrolidinium
1,3- dialkylimidazolium
N-dialkylimidazolium
tetraalkylammonium

Anion
Hexafluorophosphate PF6Tetrafluoroborate BF4NO3Hydrof luoride anion F (HF) 2,3Trifluoromethanesulfonate CF3SO3Fluorine containing anion
F(HN)nAnd so many other combination.

Application of Ionic Liquid
1. antistatic material
By adding and mixing into resin, ionic liquid can be used as antistaticmaterial. Because ionic liquid is non-volatile and possess high heat
resistance, they can be mixed into resin under high temperatureprocess. By optimizing ionic liquid structure and compatibility withresin, they can be excellent antistatic material while maintaining thetransparency. They are also known as the material not to be much

effected by outside condition such as humidity. They also have hightolerance against high temperature and can be mixed into resin suchas polycarbonate. Ionic liquid is also expected to be good antistatic
materials for paints for building, UV hard coating material, adhesivematerials and so on.

2. Electrolyte
The property necessary for the electrolyte, is to possess highconductivity, high voltage tolerance, large capacity, high tolerance
against low and high temperature, safety and so on. Ionic liquid has
high potential in this regard and they can be expected to be used forvarious types of electrochemical devices such as electric double
layer capacitor (EDLC), lithium ion battery (LIB), dye sensitized solar
cell (DSC), and fuel cell etc…

3. Solvent for synthesis
Recently in the chemical industry area, it is urgent to develop green
process such as to replace strong smelly organic solvent with otherenvironmentally friendly liquid for the reactive synthesis solvent.
Ionic liquid has high expectation in this area too. Because ionicliquid can be readily used repeatedly by separating other liquid byheating, distilling and so on. Therefore it can be recyclable andenvironmentally friendly.

4. Solvent which can dissolve (melt) non soluble
material like cellulose
Ionic liquid can dissolve (melt) non soluble material such as cellulose.
When cellulose is regenerated, polymerization degree is maintained
so that essential property of cellulose would not be changed. This

properties has the possibility to be utilized to make fiber, sheet ofrecycle cellulose.

5. CO2 Absorbance
Carbon dioxide is one of the major reason for global warming
problem. Since the ionic liquid is non-volatile and do not spread into
gas phase, they have possibility to be used for absorbing CO2
separation and recovering process from industrial waste gas.

6. Lubricant
Lubricant is widely used for various type of machineries in order tomainly to decrease the friction between substances so that energy
efficiency can be enhanced. In this respect, ionic liquid has highexpectation because their boiling temperature is extremely high sothey can be applied for lubricant even under vacuum condition.
