CONTEXT

The heat stability, the non-flammable and non-volatile character of ionic liquids make them solvents for the future in industrial processes.

Moreover, the rate of the reactions, the selectivity and the yield are often better in ionic liquids. Their non-volatility is exploited in many chemical processes.

Further, aware from environmental problems, chemists have to turn towards safer less polluting methods. The massive use of volatile organic solvents causes involvement of the chemical industry in rejecting green house effect gases. New orientations have therefore arisen through the name of “green chemistry”. Consequently, substitution of conventional solvents has experienced great development notably with ionic liquid. Their fields of applications gradually widen over the years and practically all the industrial sectors show interest for the latter.
