Ionic liquids are “salts” composed of only ions (anions, cations), and liquid compounds are particularly called ionic liquids. Generally, “salt” composed of ions is known to be high in melting point as typified by inorganic salt. However, since “Ionic liquid” with a low melting point has been reported since the early 1990s, various compounds have been synthesised and their physical properties have been reported.

There is no definite definition, and the name which has been named is various like “room temperature molten salt” or “room temperature molten salt”.

Characteristics of Ionic Liquid

  • The vapor pressure is almost zero
  • Flame retardancy
  • Ionic but low viscosity
  • High conductivity

“Ionic liquid” has these various characteristics and is expected to be applied to a wide range of fields including environmentally harmonious reaction solvent, electrochemical device field, tribology and so on.

Ionic liquid = future solvent

Ionic liquids are different in anion even though they are the same cation, and are differently affected by viscosity and exhibit different values. In addition, viscosity changes greatly with slight temperature change.

Product Information

1-Ally-2-alkylimidazolium X

We produce a new Ionic Liquid commercially. These are 1-Ally-3-Alkylimidazolium compounds that were developed by Dr Hiroyuki Ohno at Tokyo University of Agriculture and Technology.

These have comparatively high priority compared with the conventional Ionic Liquid, and melting what did not melt until now is expected.
