Ionic Liquids
Ionic liquids are organic salts that are liquids below 100℃.
The combination of a broad variety of cations and anions leads to a number of ionic liquids with diverse physicochemical and electric properties.

Ionic liquids are organic salts that are liquids below 100℃. Cations and anions may be selected depending on the purpose of use. Ionic liquids may produce a variety of physicochemical and electric properties owing to myriad combinations of anions and cations. Unlike organic solvents having a low stability and high volatility, ionic liquids are favored in numerous applications owing to intrinsic properties which include high thermal stability and solubility. Since many ionic liquids can be recovered and reused, they are spotlighted as an environment-friendly solvent.

Industrial Applications of Ionic Liquids
Ionic liquids are attracting increasing attention in many fields, including chemical solvent, plant, electrical and electronic equipment, energy, and environment, although their pharmaceutical application has been already made available.

In view of awareness of the deteriorating environment, researches are directed on developing alternative environmental friendly solvent systems that are non-toxic, non-volatile, and physicochemically stable with great solvent power on a number of materials, product recovery, and recycling ability.

In this respect, ionic liquids hold potential as green solvents that meet the above conditions. Further, ionic liquids can absorb air pollutants such as sulfur oxide or nitrogen oxide associated with fossil fuel combustion and serve to separate carbon dioxide, a culprit of global warming. Therefore, the most ideal solvent can be created for many applications

With the aforementioned properties, ionic liquids can be used as solvents in chemical and pharmaceutical industry, and they can be used for desulfurization and carbon dioxide capture. Another use of ionic liquids includes electrolyte media in condenser, secondary cell, fuel cell, and solar cell in the electrical and electronic industry. In the nanochemical sector, ionic liquids are used as stable catalysts.

As such, ionic liquids can be applied in a variety of industrial sectors, such as chemistry, pharmaceuticals, engineering, and electrical and electronic equipment. More recently, ionic liquids are used in the development of biopolymer (bioplastic)-based films and coating materials, suggesting their wider use in the future.
Development and Product Line-Up
As a pioneer, C-TRI has engaged in research, manufacture and marketing of ionic liquids since 2003.
Currently, a number of reagents using ionic liquids are being supplied to universities, research laboratories and corporations.

We have studied ionic liquids from the early 2000s and commercialized about 250 ionic liquids. We will also expand our product line-up to meet the growing demand. Recognizing that the diverse industrial applications of ionic liquids are forecast to grow since 2015, C-TRI is poised to seek a large-scale ionic liquids production. We are endeavoring to create new markets via development of our own application technology using ionic liquids.
