General information

Ionic Liquids

Ionic liquids are salts which are available in a liquid state over a wide temperature range. They constitute a new generation of solvents with considerable potential for being able to replace classic organic solvents. Ionic liquids are composed of organic cations and organic or inorganic anions. Due to their fully ionized composition they exhibit no vapor pressure over the entire liquid range.

• Low-melting with melting point under 100 °C
• Thermally, mechanically and electrochemically stable
• Neither volatile nor combustible
• Negligible vapor pressure
• High solubility of many different kinds of chemicals
